I really like my Tamiya TA05v.2.
But you probably will want to put something on the bottom to avoid pebbles jaming it up.
With your price range, you can get the TA05v.2 R kit. It come's with a lot of upgrades and you will have $ left over for more upgrades or whatever..
Or if you change your ind and want to go cheaper, the Tamiya M05(most have mini cooper bodies) Chasis won't touch pebbles and are around 100-200 and almost never break!
Wish I would of waited a couple months to get that R version!
