My first mechanical keyboard was a HHKB Pro2 I purchased around 2009ish. (I still have it)
I have a lot of keyboards, but I guess I'll share what's on my desk at the moment. At home I'm using a Midway60 LE WKL with a custom pom plate, Gateron Ink v2 Stabilizers, and 60g Sprit Supreme Gateron 8008 Minks. (8008 Inks with milky tops).
