Go to your lhs or stores and find out what trucks they have good part support for. Revo, T-maxx, Savage, Monster GT, Losi LST. All are good trucks with strengths and weaknesses. The Warhead will probably be a great truck too. Figure out what you want from a truck, and how you want to use it. Then figure out what you'll be able to easily get parts for. This should narrow down your choices.
