I believe it to be full of shill bidders as well. While researching electronic lots I discovered that the day before the auction ends there is always a bidder around 3am (EST) who places a bid that equals close to what the going rate for the item is on ebay. Its different bidder names but always around the same time with the same bid parameters. These are on larger lots of stuff like 25 refurbished cameras and similiar type auctions. It's too much of a coincidence for there not to be something fishy going on.
