AmaSuite - Amazon Product Research Tool
You can choose a category that you’re interested in, and it will show you all the data for the products in that category. Most useful are Sales Rank, Number of Reviews and Number of Sellers. One nice feature is that you can configure what Opportunity Score means to you, for example, how many reviews it should have, what price range, etc. Then to quickly judge if the product is good, you just look at the Opportunity Score. Price: $97 onetime fee.
