I've done business on Ebay, and I've found that it's pretty easy to know (most of the time, anyway) whether it's a bogus deal. I always ask for additional pictures, serial number, etc. when I'm thinking of purchasing something. If they're not forthcoming, or from a second email, etc., I know something isn't right in Denmark. I have received items that were not as advertised (my RD77 Artist most notably), but others have been exactly as described. Like Keith, I get the second chance offers, but just delete them. If one is using Ebay, one should never go for a second chance offer because it's outside of Ebay and without the (limited) protection you get going through proper eBay channels.
All this being said, it's pretty easy to tell for club members that this is bogus just by the price alone. I just hope Ebay gets these scammers off of their site.
