You might want to consider the Cybex AutoView 400 or 424. The AutoView 400 will connect you to 8 PCs and the 424 will connect you to 24 PCs. They are currently in use in our lab environments.
We also connect all of our AutoViews with a Cybex LongView. Basicly your KVM extender. You can use the LongView with almost any KVM system you already have install. We have them connected to Belkin KVMs. The extenders sends their signal over a standard ethernet cable.
WARNING - Don't ever patch the ethernet cable through a switch. You will kill the switch. But you can send the signal through a normal patch panel, if you wanted the LongView receive to be at your desk. I am not sure of the distance for the extender, but all in all they work really good.

Oh, I just looked. Cybex is now called Avocent.
