I'm a tad confused as to why you would actually want something like this.
Most sites have search narrowing functions that ultimately will give you a list of all the types of parts in any particular category. Why you would want to sacrifice descriptions, specifications, user reviews, and pricing information is baffling. Etailers constantly shop each other to maintain a competitive pricing structure. Besides, your business should go to those merchants who've proven their reliability and integrity, (take that to read Newegg, Amazon, and some others), not simply to someone who might arbitrarily comply to a standard you've imagined should exist.
