I have an HP KVM Switch For Sale (J1461A). It has 4 ports and is in great condition. KVM switches allow you to use four computers with one set of monitor/keyboard/mouse by emulating the ports. It's a great piece of hardware, and it retails for over $1000 (http://www.streetprices.com/Electron.../SP114699.html)

I'm willing to accept cash, paypal, and trades - please only serious offers. PM/Email me for more information.
