I don't understand. If eBay protects the buyer and the seller, the buyer complains and eBay reverses the transaction, then the buyer refuses to return the item, then what good is eBay? Ebay should hold the funds until the item is returned. Personally I have never had a problem with eBay or parts swappers. On larger items, I think their fees are way too large. I know on automobiles they have special pricing rates.
