Low budget gift suggestions?

I've been searching online for some trinket/budget gifts but couldn't find anything interesting. The person I have in mind for the gift is in his 60's, into tech and a geek, although the gift doesn't necessarily need to cater to his geeky side.

I'm just dropping the question here since Lemmy has a solid geek/tech userbase, and maybe some of you have better ideas than me.

TIA
