its been said above but i will say it again cause its important...
get a car you can get parts for!
if you lhs's don't support cars, then you will always have hassles gettin stuff, especially when you need it.
i currently run a tamiya tao4. its not supposed to be as good as either an x-ray or tc3, but i beat them both reguarly and i can get parts from a few lhs's
any pro level kit will win for you as long as you can get a setup that is fast with your driving style and you stay on the black stuff.
