Depends on a number of factors. First of all, what kind of layout do you like? Full-size, TKL, 75%, 65%?
It’s also going to depend on what you consider mid-tier. Do you have some examples of boards you’re looking at?
The most common one, I consideer mid tier around 80-120€
I’m not sure about Euro pricing, but I think you should be pretty close to a Ducky One Two, which comes in a few different layouts and switch options. These are really well regarded in the community and I believe they have a silent option.
Personally, for silent boards I am a really big fan of Topre, but they are going to be a bit above the range you’re looking for. They are also not technically “mechanical”, but it’s splitting hairs.
I have a whole stable of mechanical keyboards, most of which are fairly high end by most peoples’ standards and most of which I have built/lubed/soldered myself so I might be a little too deep in it, but I will say that my daily driver has been a Leopold FC980C Topre board for about the last 3 years and I have never thought about replacing it.
Niz makes some much more affordable electrostatic-capacitive boards that could potentially offer a similar experience to Topre boards within your price range but I haven’t personally used one. Worth a look though.
Idk if Ducky is mid tier or not but I have several of their keyboards and love them a ton
In addition to what the nice people here have to say, there are a few mechanical keyboard communities that you should also check out.
I can’t offer any advice myself, because my keyboard journey has led me down a niche rabbit hole to a Split, low profile, 40%, ortholinear…
