Where is the best place to buy parts kits and a full set of tools? Does being a member of GOC get me a discount for these anywhere?

I would like to buy as many parts from the same manufacturer as possible, now before you start saying I should just buy the whole gun, no! I want to do it my way! I just want your help in doing it how I want to. Lol

But seriously where do you guys like shopping?
