This is exactly the kind of thing we’ve been looking for to use around the office. According to Paladin Tools (the manufacturer), it’ll handle LAN, telephone, serial, coaxial, USB, VGA, mini-USB, S-video, FireWire, PS/2 keyboard, and parallel printer cables.
It also features both auto-scan and manual modes, runs on a single 9V battery, and has rubber feet to keep you from pulling it off the table while you’re wiggling the cable to check it.
The one pictured comes from circuitspecialists.com for $150, but street pricing starts around $135.
