ebay buyers tools

Does anybody know of any tools out there on the web used for searching the entire ebay website for auctions/buyitnows in a certain price range? Or even something that allows you bid on several auctions at once?
-Thanks!

You can use Ebuyersedge.com to search eBay and narrow down your search using the advanced options, but you can do that at eBay just as easy. However, you can set up saved searches on ebuyers so that you would get an e-mail when a new match is listed.

You can use a sniping service to bid on multiple auctions - hidbid, auctionsniper, etc.
