It depends on where you are located. I get the fastest shipping and the best repro parts from Snyders. Berts has probably the largest collection of original and new old stock parts in the world. they also have the new repro parts that others handle. Like Snyders, Brattons sells the best repro parts that are available. The Brattons catalog is the easiest to navigate and has the best information of any of the how to books that I have seen. Bratton lists most of the bolt sizes and threads per inch. this helps a lot when you need to chase threads and don't know what size tap to use. They list all engine specs and clearances, exploded diagrams of most parts and the best wiring diagrams and legend info that I have seen.
