I have the CM Quickfire Pro w/ brown switches and its terrific. My only qualm would be no palm rest, which I really like. I also have the Levetron Mech 5 w/ blak switches and its really nice too, with included palm rest.
After gaming on both (fps and tps), I can say that I prefer the browns: lighter actuation so little less effort, and I do like the actuation. Both are nice though.
The CM Quickfire pro has been on sale recently for ~$60-70, down from the $95 I paid.
