How many old phones, digital cameras, and MP3 players do you have that still work but are sitting useless in a drawer? A site called SecondRotation is like the company BuyMyBrokeniPod that Mike wrote about a few days ago, except you can sell more than just iPods. SecondRotation will take practically every brand of cell phone, digital camera, gaming console, GPS device, and MP3 player (including iPods and iPhones, but not any that are bricked, unfortunately for Mike). To get an estimate takes about 20 seconds. You find your device, check a few boxes detailing its condition, and you get an estimate on the spot. They pay for shipping. (See CrunchGear’s take).

The site launched in July, and bought about 850 items last month from consumers (up from 150 in August). The Waltham, Mass. startup has raised about $2 million in angel money and is working on raising another $1 million to $2 million for the third tranche of its A round of financing.
