Source for DVI/USB KVM switch, cables

[Kent Johnson]

Hi,

I need a KVM switch that will, at a minimum, switch one DVI monitor at 
1920x1200 and one USB port between two computers. An extra USB port and 
audio would be a bonus but not required. I will also need the DVI and 
USB cables to go between the switch and the computers.

Can anyone recommend a particular brand or supplier for these? They seem 
to be pretty pricey. For example this unit

which is $149 from NewEgg, including the required cables.

Thanks,
Kent
