I can think of a few that have served me well:
- A good laser printer: $100 plus a few reams of paper have covered my printing needs for over a decade (and going)
- Wool socks for the winter. Makes dropping the thermostat a degree or two much less unpleasant
- A good, 100W USB-C PD charger. I've got a few, and they'll charge/power pretty much any of my devices (including laptop).
Almost any repair tools, gardening, or anything NEEDED to DIY. You can do a lot of personal projects with very little money.
That being said, it's very easy to fall into a trap of going beyond what is needed into a full, fancy workshop, with all the shiny new equipment. If that's what you're goal is, that's fine. If you're doing it to save money, there's a lot of ways to just get the bare minimum, and be extremely effective. Especially if you can get used, or even non-functional equipment and fix it up yourself.
I have recently needed to travel for work and my duffel bag was a pain in the butt to carry around the airport. All the rolling bags I saw for purchase didn't seem well made and were pretty expensive while somehow not utilizing all of the available overhead space. Even well known brands like swiss gear seems to have critical break points on their luggage. The last trip I made, I noticed that all of the flight crew used the same brand of luggage that looked very well made and was reinforced in all the right areas. So I looked it up and found that their non-commercial line was just as shitty as everything else I was seeing, but their flight crew line was top tier... But only flight crew could buy it. So I found a website that would sell it to me! $240 for a suitcase that looks like it will last my lifetime and fits the exact dimensions of the overhead space saving me $40 per trip to not check the bag (my company doesn't cover checking bags). Return on "investment" is 6 flights or 3 round trips. The brand is Travelpro for anyone wondering. And the site I purchased from is mypilotstore.com. They even sell spare parts such as wheels/bearings or leather handles. Super happy with my purchase!!
- A good quality belt. A cheap belt may last a year or two while a good one lasts decades but doesn't cost 10x as much.
- Any sort of micro-mobility device (bikes, scooters, etc. or even costlier electric versions of these) that replaces a regular commute has good ROI over driving or even public transit (unless you're lucky enough to live in a city where it's free).
- A big sack of rice. It's kind of insane how many meals you can get out of one of those.
My wallet cried a little when I bought new bike, then I calculated the cost of alternative (car, public transport) and was surprised that even nicer bike is cheaper.
If I count only operating cost of car it will pay off in about 1 - 1.5 years. Public transport is at about 2 years.
Yes I know that I have some infrastructure, and other things that make it possible for me to use it everyday as car.
Also I stay fit and healthy when I don't sit in a car - so this is another value that can't be easily put in monetary perspective.
Quality cookware.
If you're into miniatures, be it for painting, playing games that use them, or just showing them off, a resin 3D printer. Make Games Workshop and Hasbro pull their hairs out and have fun with a huge amount of stuff you can print!
A nice Elegoo Saturn 2 or Halot Mage printer + 2 liters of resin are enough to print well over 400 miniatures of 28mm-32mm scales. Even if you account the pre and post print work (putting supports, cleaning the print), it quickly becomes cheaper than buying boxes of plastic minis. The learning curve, amount of things to account for before printing and maintenance are all significantly smaller than a filament printer
Laundry machine, whether at home or laundromat. It’s one household chore that almost nobody does manually in the developed world.
Hot water heater. It’s almost dirt cheap to run, but damn if I don’t love me some hot water.
Refrigeration. Shit is so cheap and ubiquitous, but fucking ice and cold beverages, hell yes.
Cannabis. It’s not free but it’s really not expensive. A little goes a long way these days.
Internet maps and GPS. Usually you don’t have your pay for the maps, or GPS, but somebody has to store and update all that information about places you’ve never been. Also phones and data connections aren’t free. Trips used to take a lot more planning, and getting lost. I think a smart phone is worth its cost for mapping alone. And it also calls people too. And plenty of other amazing stuff.
A bidet. You can get a basic one for $30-$40 and there is no need to get anything fancier than that. With the amount of money you save on toilet paper, it will more than pay for itself in the first year.
Additionally, toilet paper will never clean your rusty balloon knot nearly as well as a stream of water. If you got shit on your hand, would you be satisfied with wiping it off with some paper? I hate pooping anywhere else but shit-base-alpha. Whenever I have to poop somewhere and use toilet paper, I feel like a filthy caveman.
Decent stainless steel 'silverware' that doesn't easily bend will last a lifetime isn't very expensive for a one time purchase, and can be really cheap to pick up used if you aren't too picky.
Cables.
Like, just buy a bunch of USB-C cables; they're cheap. Maybe some HDMI and audio ones. Maybe splurge for the braided ones if you want to be fancy. It saves you from the problem of only having one that works that you have to keep juggling around, or not having one on hand when you need it. Different lengths and colours as well, so you don't have super long ones going all over the place, and can distinguish them at a glance.
Instant Pot
Depends on your hairstyle, but I used to have my hair cut about once a month for $20-25. I bought a set of electric hair clippers for about $30 more than 15 years ago and learned to cut it myself and have saved thousands of dollars. Its a simple men's cut, so it works for me.
An electric razor or a quality safety razor are also possibilities. I used to use the disposable gillette razor cartridges at about $4 per head, which lasted 3-4 weeks (I used them until they hurt to save money). Now I have both a safety razor and an electric razor (I don't need both, the electric was a gift). The safety razor was $45 and and blades are about $0.10. Blades last about a week instead of a month, but it paid for itself in about a year. I experimented with various shaving creams as well, but eventually went back to canned shaving cream because the time spent creating a good lather in alternative forms was annoying and not worth the savings.
The electric razor may or may not pay for itself depending on how much it cost and how often you have to change the head and the cost of cleaning solutions, but I do enjoy having it for a quick shave. It definitely is not as good of a shave though.
Glasses for my myopic ass. Face I mean.
A 3D Printer and CAD software, especially if you can get around free software.
Break a plastic thingy, why spend $50 on a replacement when you can make one. On no that broke, learn why and make it better.
I’m at the point where I can 3D print small tablet cases, and it’s funny watching the included injection moulded accessories fall apart, while mine is going strong.
It’s not for everyone, and there is a skill gap that’s bigger than most people are comfortable jumping. But if you have the desire/want to learn CAD or 3D printing, it will pay for itself, if you use it right.
Dried beans.
CeraVe unscented lotion.
Sunscreen
$100 a month for family membership to yoga studio
My iron skillets, none were over $25. Some are over 25 years old now though.
Toyota Tacoma. Is literally worth more now than when I bought it. My model has bluetooth but none of the "always on tracking" many vehicles come with after. Subaru Forester. It had a recall for a head gasket something or other that required an entire new engine. Got that done at 115k miles, basically a new car for nothing.
Le Crueset set for about $600 15 years ago. We have cooked hundreds of meals with them. Same with cast iron and stainless copper core pots and pans. Immersion blender (corded) as well. Stove top espresso percolator is so cheap and nice if you aren't a daily espresso drinker. Having that one cup on a rainy afternoon or after dinner is a treat.
If you like grilled/bbq/smoked food, a nice grill will last years if you take care of it. I had a side by side gas and charcoal/wood grill for the last 11 years. Heavy use and lack of replacement parts finally killed it. I could cook full plates for 20+ people off that thing or just a couple of chicken breasts for a quick dinner. I have a pretty cheap but capable gas stainless grill and a santa maria bbq now. They work fine, but not quite as convenient as the all in one.
A really good mattress, solid bed frame, nice pillows, and high thread count cotton sheets are worth every penny. I didn't get all that together until I was middle aged and I really wished I had done it sooner. My back is like "wtf dude, we could have had this the whole time ?!"
If you do any woodworking, 3d printing, making stuff, art etc? Space. A space to do all that it. Wether it is a hobby or cottage industry, you will need dedicated space to make your mess. I've seen people trying to DIY in apartments on youtube and its just so bad. Not to mention dangerous. Fumes, fire, trip hazard, mdf dust, etc. Find a place to house all that nonsense outside of your living space.
And if you make digital art, photoshop, draw, anything that makes you hate a mouse for input. A Wacom tablet screen is worth it. Not an iPad, not a Surface all in one, not some knock off clone from Ali Express...but a crazy expensive Wacom. The regular tablets are okay, but drawing on the screen is almost impossible to come back from. I bought mine in 2009 for $3k and still use it daily.
3D Printer. You'll probably need to learn a bit of 3D modeling to get the most out of it and it is a hobby in its own right... But man, the amount of little bullshit stuff I had to buy from Amazon that now I print for pennies and to the exact specifications that I need. I made a new door shelf for my fridge to hold my coffee carafe, a door stop, a loop for my bedside table to hold cables, bracket to hold my webcam, hydroponics tower, drawer organizers, pegboard hooks, a plate to cover a weird shaped hole in my wall, a bracket to hang a rgb smart bulb behind my monitor, a phone stand, angled smart doorbell mount, broom and mop hanger, board games, and of course attachments for my 3D printer!!
Might not be the most popular call, but streaming services.
A) movie tickets are absurdly expensive. Went for the first time in years last year and was shocked by the nearly $60 for an early morning session. Bonus though because the wifey and I were the only two at the screening (spider-verse 2). B) physical formats can cost more than 3-4 streaming services per month for just a single movie, cd, vinyl etc. Sales are still worth keeping an eye out for. C) streaming services promote choice. Your favourite movie isn’t on the service? Watch these similar themed movies. Like this song? Here’s work from similar artists. D) the other high seas streaming service is very viable if you’re discriminated against by living in a particular region or country. Or you simply can’t or don’t want to pay.
There’s definite downsides such as service saturation, the curse of too much choice, or constant garbage with the odd diamond thrown in. But if you’re not too concerned with loyalty (and you shouldn’t be) or you sail the high seas then that’s not going to be a problem.
LED lighbulbs.
Started getting them way back when those things were quite expensive and they still payed for themselves within 2 years.
You can use bigger more powerful ones to get more light in a room, which makes your home much more pleasant without your electricity bill going through the roof.
And this is just plain bulbs, no extra installation work stuff. If you go into stuff like LED light strips you can surround yourself with light and/or pimp your home to your hearth's content.
There is really is no need to live in a place that turns into an almost cavelike somber environment when the sun goes down.
Personal hygiene products.
Toothpaste and deodorant.
This is highly individual, and I have some expensive products to add....
A good dedicated camera, since I got my first proper camera back in 2017 (a Lumix GX80) I have taken tens of thousands of photos per year.
Last spring I upgraded to a Lumix S5 with few fantastic lenses and it has been awesome, and with my S5 and 100-400mm sigma lens I have goten plenty of great photos.
To me my cameras are in my top three ever best purchases, all the things I have went snd done because I wanted to take photos have more than paid for the money invested, perhaps not in direct money for me, but in inspiration and enjoyment.
I am planning on getting the Sony A7 IV as a complement to my S5 as the A7 IV has much better and faster autofocus, I love my S5 for it's amazing colors, UI and overall performance, but as I often go planespotting I need better and faster autofocus.
Damn, that was a lot of text about cameras....
Time to talk about cars...
I bought my first car last summer after getting my license back in 2022 and living alone without a car for 8 years.
It is a 2021 SEAT Leon FR PHEV hatchback and being able to get to interesting places out in the country to get cool photos have been fantastic and really improved my mental health.
It was very lightly used, and has enough performance for me without being exsessive.
I mostly drive on battery and charge up once a week, since I live in an aparment complex we only have shared charging infrastructure, but since it is a PHEV I can still go far when I need to without worrying about chargers.
WD-40.
