Windows 7 - DVI KVM Switcher

I'm looking for a DVI KVM switcher so I can hookup two desktop computers (one 32-bit & one 64-bit Windows 7 Home Premium) to one monitor and I'm wanting to switch mouse, keyboard, and sound. Also having the choice of using USB or PS/2 would be nice.

Is this one from monoprice a decent one For only $103.82 each when QTY 50+ purchased - 3-Port DVI Audio USB & PS2 Combo KVM Switch with Cables - Retail | DVI KVM Switches ?

My Logitech Duo Manuals for Cordless MX Duo & http://www.bitbenderforums.com/~alak...duo/logi08.jpg lets you use either one single USB or two PS/2's (by way of a USB to PS/2 adapter plug) from the charging station into your computer and I've always used the single USB plug which connects both the mouse and keyboard.

Since the monoprice KVM appears to have separate mouse and keyboard USB input ports would I still be able to use the Dual's USB connection?
