guitarboy, just about all your hobby-grade R/C replies have something to do about making a vehicle go to a posted speed...
Seriously... Post something about the vehicle's features, not how fast you can get them to go...
Anyway, the RC18T from AE is correct. Its a great RTR for getting into hobby-grade, and its only $173 at Tower:

AE also sells the top of the line factory team (its a racing model, not an alloy 'toy'), but if you're just getting into hobby-grade, the RTR is what I would recommend.
It has everything you need to get started, a battery, charger and transmitter. All you need is 8 AA's for the transmitter.
The 18T is also very popular for its amount of hop-ups. They're lots you can do to it, such as creating an alloy monster, or carbon and brushless track monster!
Its a shaft-driven 4WD, so drivetrain maintenance is at a minimum compared to that if you had a belt-driven one (though some people, including myself, prefer belt-drive over shaft-drive).
The 4WD will help you get through almost everything in your backyard. A big advantage compared to 1:10 2WD (RWD) stadium trucks. (I'm not saying 2WD stadium trucks are bad, as they're the fastest class of R/C trucks out there, but for someone just getting into hobby-grade, especially if you don't plan to race (often or not), 4WD will be something you'll really learn to appreciate.
Hope that helps!
