For the low-maintenance, electric, durable and tough areas you could look into the SC trucks. The Slash seems to be the basher's favorite for it's durability while it doesn't do as well on the track because of its high center of gravity. HPI, Losi, and AE all make good SC trucks too more for racing.

Power and speed would require lipo batteries with a mod motor. It just depends on what you're trying to do (bash or race in a certain class). SC trucks aren't the fastest of the bunch, you might want to then look into a buggy.
