Shop around though. You know how CompUSA's prices can be compared to online.

Although right now they seem to have some nice prices on IOGear stuff, with rebates as well.
There are a lot of brands. There've been threads here about "which is better" and whatnot. IOGear makes nice looking compact-size KVMs, but I've never used them. I liked my Belkin Omnicube when I've needed to use it. Also make sure you get one that will support your mouse and keyboard, as some of the "extra features" may not work, especially non-Microsoft brands (USB stuff should work perfectly well though).
KVM stands for Keyboard/Video/Mouse by the way.
