I purchased my Burley frame on ebay. It was exactly what I expected and wanted. A great transaction. I always look at feedback. I've heard some say that they won't go below a certain percentage, but if I'm buying something for more than say $50, I read all negatives carefully and the seller's response. I won't bid if they are a)rude b)do not have whatever selling nicely displayed, it shows that they probably take care of their stuff. If it's in the middle of crap, they don't care. c) If they have even 1 negative with the buyer having issues with it not being as described or pictured. d) won't take paypal because you can use a credit card on high dollar items and that will give you some protection also.
I've only had one bad buying experience and it was here on TE, not ebay, and the paypal arbritation is a joke, so use a cc. I've had almost 1000 transactions, but be careful careful careful.
