Shopping around for a good KVM switch

I am using a re-badged GEM GL150L. Here is its specs: http://www.scanport.com/lcd_spec_gl-150l.html

I need a 2-PC switch that won't cause visible ghosting at the monitor's native resolution of 1280x1024.

So far I've narrowed it down to the following item:
Linksys ProConnect 2-Port Compact KVM Switch Kit, PS/2 with cables. (Part - PS2KVMSK)

Anyone have experience with that switch under similar circumstances? Could use some advice here.

Btw, incase it makes a difference, the two machines I will use this one are my primary gaming/work machine (which is currently on the drawing board) and a Linux box for learning/mutilating (my current machine). The gaming machine will probably use a Radeon9700. My current setup is using a Radeon8500.
