They have a lot of parts on the webstore, but you're right, they also have a lot of parts that aren't yet visible there. That doesn't necessarily mean a given item is unavailable. The staff is dedicated, but small and very busy. New items get added to the webstore as time permits, but it is a fairly involved process. Getting orders filled and shipped out rapidly is the priority. All that said, references and links to direct competitors are like fingernails on a chalkboard on this forum. I'm confident that acme light line parts would feel the same way about folks linking to IHPA on acme's tech forum. Business owners tend to get protective of all things associated with their livlihood for good reason.
