I can find most suspension parts at my LHS and they are starting to stock more and more. They carry all the electric parts. The Nitro they are starting, but haven't been out long enough to stock everything. As far as ordering from tower hobbies, they are awesome I just ordered $50 worth of parts for my duratrax from them(to stock up) and they charged me 3.99 shipping for everything AND I got it the next day!!!!! Now I do live within a few hours of their warehouse, but still very nice company to deal with.
