I've had 3 boards.

Atrix Sniper Keyboard. $25 at GameStop, resoldered switches to upgrade it from Outemu brown to red

Then later I bought an white rk61 with blue switches, put a stronger spring inside the switch on the spacebar (why not?)

And then of course I had to get a $10 keyboard at the thrift store (Punkston TH61S, unbranded optical yellow)

edit: I also spray painted the plate blue on the RK61
