I would personally perfer this
keyboard . It seems like it would be alot better then the Z board, but it comes at a cost. I have never actually purchased a keyboard I juts picked up ones noone was using and never really cared about their quality. The only real problem with keyboards that I have had is this annoyiong MS one I'm using now. It requires you to press the f lock key to use the f keys. I'm not sure if I would be willing to pay more then 50$ for a keyboard. FPSes are the only games I really play that much and all the key layouts are pretty much the same.
