I was looking at the X-terminator Delux. It comes with many upgrades, high torque metal gear servos, carbon fiber radio tray, a glow plug, a fuel bottle, and new shock towers to name a few. The delux version sells for $446 at me LHS (Hobby People). I've heard they are extremely powerful but be careful if you want to race because the Xterm comes with a 2.47 engine. Hope this helps your decision.
