While I prefer Google for most of my searches (much like Gregg who told you about Froogle), there are many folks out there who prefer All The Web/Fast, and there are some things you can do with ATW that you can’t do with Google (MP3/FTP search comes to mind). One neat feature is the ability to skin the site. They recently had a contest, and you can view the winners here. I prefer Retro-Active.
