Wow. Thank you.
I flirted with the "mech" community for a while a couple of years ago, and ended up with two boards:
A KBParadise V60 with Gateron Browns that I use as my primary keyboard for my desktop. That's mostly a gaming machine for me, but I do code on it quite a bit.
A bluetooth keyboard with low-profile Gateron Blues that I used with my iPad 6th Gen for coding (I use Blink to SSH/MOSH into a VM). That was a good keyboard but the feet broke off, then I upgraded to an iPad Pro and the Apple keyboard cover. It was collecting dust, so I gave it to my 11-year-old.
The GMMK looks like exactly what I was really looking for, for desktop use. I've got some research to do :)
