Oh yes, it's similar to a lot of other 'enthusiast' things, like high-end audio, cameras and guitars.

I got into keyboards because I wanted a lockdown project. I figured I could learn a little about electronics and firmware, learn how to solder, and even perhaps make something that would be useful at work. Keycaps can be a complete rip-off, and my keyboard is fitted with a mixture of caps that I've scrounged from various places.

And when we finally get back to the office, a super-noisy mechanical keyboard will help my project of being allowed to WFH as much as possible ;-)
