I don't have any advice on What Brand... I own a Revo 3.3 and its OK. I bought it used and this is where my advice starts... I thought it was a great deal untill I learned something about RC... It was all worn out. I paid $300 for it, it came with 2 bodies and some tools. It needed a Starter battery so I could not hear it run when I bought it...
I got the engine to run, but it was WORN OUT. I ended up buying a new engine for $159 plus $12 shipping. (Traxxas ERP is useless in Canada, NO LHS will honor it). Then I needed a new one way bearing $25, Tank seals, pivot ball boots, axle boots, body clips, starter battery, and Hubs... the Hubs must have been alomst shot, cause they stripped in about 2 quarts of fuel (driving on dirt).
You don't notice all these little things when you're excited about your first nitro(and you finally convinced the wife). But you sure pay for them later.... I am into my Revo for more than a Brand new one and I still have an old truck with stripped bolts holes and worn parts.
I know it expensive, but wouldn't you want to be the one who wears it out first ?
Save the headaches, save for a little while longer, and get the new truck. My $0.02 worth.
