Bang-for your buck to get everything at once the 2.0 RTR is actually the way to go.

Main difference: Frame, shock towers, shock caps and diff cases.

RTR has stamped/plate cut frame and shock towers. Slightly heavier, not the "flex tuned" setup, but it works around 85% as well most of the time. Shock caps are plastic instead of metal and I believe it gets the slightly heavier but more durable HD diff cases.

So, if you need a radio/servos/starter box all together and don't aren't brand loyal already it's a nice place to start.

I'd go RTR, learn the truck, eventually ditch the frame for a BCE and the towers for the new KingHeadz setup and never look back.
