I broke down and got a Das Keyboard Model S with Brown Switches for home. It is great, Can't recommend their keyboards enough.
I've got a Corsair K60, reasonable build quality with Cherry MX red switches. I also have a Unicomp Model M, great keyboard with IBM-style buckling spring switches. For gaming I like the extremely low activation force of the Cherry Reds, for typing the Model M is the best (even better than Cherry blues.)
I've been using the CM Trigger Z with Cherry MX Brown for a while now, and I'm a convert. Mechanical is really comfortable and responsive, not to mention the N-Key rollover and all the other features. I like the tactile bump of browns, which is why I didn't go for reds/blacks which I feel I'll press the wrong button accidentally a lot more often.
