I ordered this on a whim and got a cheap set of keycaps off Amazon for it, but now that I have it put together (plastic switch plate, tape modded, gateron cap golden yellows, double o-ringed keycaps) it is sounding and feeling really good. The keycaps were a cheap but they are bright and fun. I might make it my "throw in a bag and take into the office" keyboard.
Haha its actually a Neon Genesis Evangelion themed keycap set so the additional keycaps are icons of the angels. I have them wired up to Vim and AutoHotkey shortcuts.
