Retrevo Gadget Search Engine
Retrevo is a domain specific search engine for consumer electronics aka geeky-gadgets. A search for my preferred MP3 player (iAudio A5L) turned up some good results. None of those e-com shopping-front pages which masquerade as a review-page just because they have a 'user-reviews' section which talk about why a particular device 'is teh suck'. It even filters out Amazon product-review pages. Blog reviews are indexed however which is good. It also manages to filter splogs (spam blogs) which is again great. The search results can be viewed in a two-pane with the right side providing a preview of a particular search result.
