Useful (and Cool) Site: Buymytronics.com
I love this site, and although it's not new, it's definitely cool. The site promises payment within 48 hours, and all you need to do is fill out a handy form online to figure out what your pieces will be worth, and alert them to what you'll be sending. If you have some broken electronic junk around, then I recommend you check out this site to make a little extra cash. Did I mention that it's also not bad to look at, either?
