Check out this vertical shopping comparison site I wrote: RouterComp.

It's a shopping comparison search engine, mostly for Computer Networking equipment. It uses the Ebay API and the Shopping.com API to show prices and product specifications for both Ebay auctions and online merchants.

RouterComp can help you decide if it's worth buying from Ebay or just buying from a store. It has some stats on pricing and it's easy to compare buy-it-now vs auctions vs other online merchants.

It's not quite Froogle or Become.com, but it's pretty cool to be able to leverage APIs to do something similar.
