Iceberg.
I don't trust Ebay, and won't use it; it's a carney's dream.
I've had problems twice on eBay since I've been a member (7 years).
Between the eBay reporting system, PayPal, Square Trade and the Post Master General, I've had no problems resolving them.
Actually, there are some small sellers who are quite ok; they sell that way because it's the most cost effective. It's the power sellers you have to watch out for.
And if you are trying to get something for nothing, you can be sure you're going to get nothing much for something.
