Yup. Your options here are not limited at all.
For offroad, have a look at the E-Savage by HPI. It's ready-to-run out of the box. If you don't want an MT, you can go with the Associated T4 or B4. There are also Traxxas models that are electric, like the Rustler, Stampede, and E-Maxx. The Traxxas models (except the E-Maxx) have a factory brushless option.
For onroad, you have just about as many options. HPI's RS4 and Associated's TC3 are the fore-runners of the bunch.
As for speed, out of the box, they'll be fairly quick. With a few drive-train hopups, you can slap in a brushless system in any of these electrics, and take it from somewhat fast, to insanely ballistic.
You're only limited by your wallet.
