Duratrax evader BX/ST i say, they come with lots of hopups as standard, and have a photon 20T motor (fairly powerful).
They cost $230 AUD from tower hobbies with EVERYTHING you need, including ESC.
They are covered by a 1 year stress tech warranty for suspension components etc.
Basically if you want a machine that will go *anywhere* you need something like a buggy or a stadium truck
