In my spare time, I'm working on http://fivestar.io, which gives you the best Amazon item for a query and breaks it down by price range. So you can find the 'best' product based on relevance, popularity, reviews, and cost, without having to compare reviews and popularity yourself.
The results still need some work; sometimes Amazon's API returns illogical price brackets, so a fallback is necessary, but I'm pretty happy with it at the moment.
