I don’t use eBay very much: it seems unless you are buying something inexpensive it’s doesn’t save you a lot of money.  Anything expensive you have to do a lot of background checks on the seller to be sure they are legit and are selling products that are backed by warranty by the manufacture.  I have a lot of junk; and I have been wanting to either sell it on craigslist, or perhaps eBay.  I ran across an interesting article on selling your stuff on eBay that if you are like me, you might actually take the plunge: http://lifehacker.com/software/hack-attack/a-sellers-guide-to-craigslist-305845.php
