hpi baja 5b with a ddm pipe and airtronics m11 2.4ghz controller.
that should fit your price range.
:P Let's hope it still runs with that much wear, rofl.
On a more serious note, an MGT3.0 is probably the best fit to your needs. IT's got good ground clearance, reverse, highly durable, etc etc. A close second is an HPI MT2 and a CEN Magnum NX tied with it, but neither are anywhere near as good a basher as the MGT is. They lack the ground clearance, and neither have reverse. They'd both outhandle it out of the box, hands down, however :P
The aftershock will, after a fair amount of time, end up costing closer to 500 bucks. The trucks I've listed will run great right-out-of-the-box, and have decent engines and good durability.
