If you're thinking of racing at all then go truggy w/ brushless conversion. Look for ones that have conversions for them. Tekin makes some of the best conversions on the market and they have them for the RC8T, 8ight-T (both 1.0 and 2.0) and MBX5T and 6T. Probably some others as well but those are the ones I'd look at.

I have an 8ight-t 1.0 w/ tekin and it's awesome, I don't bash hard so I haven't broken anything in neither that or the erevo brushless but 1/8 truggies are just built more durably. Aluminum chassis, shock towers... etc.
