You have the opportunity to give "buyer" feedack on a seller. Sellers do not want bad reviews. It kills future deals for the seller. My husband uses Ebay all of the time with no issues. He did sell a car once and the buyer backed out. My husband was not pleased and his seller review reflected that. The checks and balances in place on Ebay affords some assurance of satisfaction.
I was so tempted to jump into the bidding on that machine but at that price, albiet awesome....i want to run it by my husband. He knows that I want to upgrade my machine but at the $5,000 range, we need to talk.
