i really like it, the search works well, the design is nice...well done!
the auto-generated name thing is a great idea, but I wonder if you could increase the conversion rate by replacing the copy "Create an account now, so you can choose a better name for your wish list!" with the form itself. That copy makes it seem as if I need to register in order to select a name, but in reality selecting a name (and making a password) is the registration process.
one question: are you only pulling products from amazon and newegg currently, and if so, plans to expand?
