I buy lots of stuff on ebay. Never had a bad experience, but I won't bid if the seller's feedback is less than 99% positive. I buy mostly jewellery findings, sterling silver and some pet stuff, even urns. I really like buy-it-now items. There are some things you just can't get in the boonies. I can almost always find what I'm looking for on Ebay and usually at a reasonable price.

My sister did get ripped off by an ebay seller who never delivered the stuff she bought. Apparently she pulled the same scam on several dozen people and was actually charged with fraud. Sis never did get her stuff though.

I sell my beads and jewellery on JustBeads.com. I have three auctions up right now and will likely list some more tonight, if I don't kill my camera trying to clean the sensor! It's a little less intimidating than ebay for me right now! I will probably sell on Ebay eventually too. Link to my auctions: http://www.justbeads.com/search/ql.cfm?s=868603821
I sold a set last week that got several bids. That was fun!
