I dont know about you guys, but since Great Planes now taking over for TD, moving out the other guy, makes part support easier for all the LHS to stock or obtain. Everyone has mention how Tower Hobbies has solved all the problems, but it is GP/ LHS supplier that is the cure. Support the LHS, and they'll support you.
Any LHS that has a GP account can order even just one part, there is no minimum.
I rarely buy from the internet stores..only if I must.
