The original poster "Yellow Wingers" is correct -- you need to be careful and do a LOT of research when buying on eBay. The item he mentions does have strange feedback. The first thing to do when shopping eBay is READ the feedback. Pay attention to who posted it, when they posted, and what they said. The first thing I noticed in the item he mentioned was the times of the feeds were all within a few minutes of each other. Then I saw many used the exact same phrase. Many of those were no longer registered users. This is what happens when eBay finds someone commiting fraud. They lose their account. So, the theme here is "buyer beware."
Anyway, I have done a little business on eBay, and have been fortunate to have had all good experiences. I purchased a Jaguar XJ6 on eBay in 2001, and sold it there in 2005. Properly used, eBay is a great buying and selling tool. Just be careful.
