I own a mechanical keyboard. An Ikbc that I bought from Amazon. I bought it because it has cherry switches. (Cherry brown I think) It has a good feel, it's pretty quiet, ahd hopefully I'll get better life than with a membrane keyboard.
IKBC is one of my favorite brands especially considering they're a sister company to Vortex and their keyboards are very inexpensive for the premium quality you get. I actually have an IKBC I use for my server (MF87).
I build my own. I have built a TKL, a few 60’s and a JD40. The 60’s are my favorite. I use GH60 pcbs, custom plate from lasergist, black cherry switches with pbt thick keycaps.
