Keyboard multipress probs

[exitor]

I just bought the low-end logitech keyboard and everything is great except I get the beep with some multiple keypresses, specifically holding W and D at the same time, which sucks when I use the WSAD setup for gaming. It also happens with E and F in the ESDF, R and G in the RDFG, etc. Is there a cheap keyboard out there that has good gaming keypresses and doesn't have multi keypress probs?

I heard USB keyboards don't have the problem, is yours PS/2?
