I ditched eBay a long time ago. They're making it very difficult for a seller to actually make a profit.
The whole scheme they have with holding funds is also ridiculous, so I will never sell an item there anymore.
Craigslist is actually a pretty cool place to buy and sell, even though there are a lot of duds there, it's free! The site just connects people, and the transaction takes place in private.

I have bought and sold items here on APUG, and I've always been happy with it. I do find that the classifieds system here could use improvement, but it works. And as a community it's nice to be able to perhaps even purchase things from other people you already know somewhat.
