Thanks guys, four is enough for me.....will be looking for MX Clear, White and Gray keyboards from here on. I already have mechanical keyboards with MX Red/Black/Brown/Blue/Green/Clear, will be going for other switch types. BTW, of the four Topre, I'm using three of them as my daily drivers for three rigs.....along with a Leopold FC660M Clear and a Keycool 84 LED Black.
