Extra Cash for non working items?

I came across this a few weeks back - I haven't tried it but it sounds like fun... www.secondrotation.com - pays cash for non working cell phones, pda's, camera, video cameras, laptops or other electronic devices. They will estimate the cash they pay before you send it. Sounds like a great way to keep electronics out of the dump and out of the environment and get a little gas money in exchange... let me know what you think!
