Best way to fetch Amazon's top selling products in a given category

Question

I'm looking to fetch Amazon's top 1000 (or as many as possible) best selling products in a given category. After scanning the Amazon Product Advertising API documentation and reading through a couple of questions on similar topics (namely Amazon ECS API to fetch 1000 top selling books and https://forums.aws.amazon.com/thread.jspa?threadID=98920), I'm still not sure whether I should be using the Product Advertising API, reading from an RSS feed or building my own scraper to acquire this information. Just to reiterate, I'm looking to fetch more than just the top 10 products, if possible (even if it takes multiple requests).

Any thoughts?
