What kind of off roading were you looking to do? There's all sorts of stuff from monster trucks, short course,1/10 "stadium", 1/8-1/14 buggy, truggy (which are basicly a larger scale version of the stadium truck), rock crawlers and their off shoots, scalers (since you're into models, you might enjoy that), rock racers, Formula-Off Road (also known as FOFF ) racers.
