I guess it depends on how much you want to spend. I kind of like associated myself, so the RC8T(or RC8te is the electric) would be their offering. Mugen makes a great truggy. A used MBX5T, or new MBX6T would be good. Losi is good too. If you are looking to spend a little less, the Thunder Tiger ST-1 is pretty cheap at about $300 rtr with a nitro engine. Then sell the nitro stuff and do a conversion and you have a very tough truggy for a good price.
Anyways, there are lots of options out there, just look around.
