My local craigslist is where my for-sale items now go. Sure, I may get a little less than top-dollar for an item, or it might take a little longer to sell, but I'm never left with some after-the-fact dispute where I have no control (note: I'll only accept cash).
eBay was fun while it lasted, but then it became a giant flea market with basically semi-pro retailers looking to sell things, and a whole bunch of random scammers. Intermixed in all that was the occasional legitimate "amateur" seller.
For the very few times I've purchased something on Ebay in the last few years, it's always been from "pro" sellers with storefront type setups. The hassles of dealing with amateurs selling poorly described items, taking too long to ship, etc. was also not worth the "deal" I was getting.
A true "amateur to amateur" auction type sales website is an area begging for competition...
