KVM Switch Using Win & Linux

Looking into buying a KVM switch so I can conserve my desk space. I have a PC that I run WinXp on and another that I am going to set up with Win2000 Pro and Linux. I've looked at different sites that sell these switches, but I am wondering if anyone can recommend the best one.

I want a switch that can handle most versions of Linux, as I have not decided on which version I will end up using, and a switch that has shared audio and has USB ports.

I've looked at Zonet and Belkin.:sad:
