considering that a few links in this thread are dead eg. specific eBay auctions and that the same sites came up in a couple threads, i decided to go through all of the links up to date and re-post all of the ones that are still active as well as sort them into categories for easier browsing. i also added a bunch of comparison shopping search engines besides the original froogle post.
hope this revised list helps save some time
