ECX vehicles are a relative bargain but the greatest downfall of the 2wd vehicles is the steering system. Specifically, the servo saver. It serves its intended purpose well and protects the servo but the plastic "C" spring is softer than necessary and hampers the response. The truck can feel vague and lazy. Although, to a new driver with limited experience this is likely not an issue as they have nothing else to compare to.
One truck that doesn't get enough recognition is the XXX-SCT brushless RTR. Yes, it's an older design and you don't have the parts support like Traxxas, however, the truck is based on a racing style platform, it shares many parts with the XXX-SCB, it comes with a water-proof Dynamite brushless system, a Dynamite 2S LiPo battery, a basic charger and a Spektrum DX2L radio. For a click over $300. You can probably find a deal online if you search hard enough. It will handle better, than any of the basic beginner trucks, has aluminum threaded shock bodies, steel turnbuckles, and the transmitter has a 3-position throttle limiter switch so you can tone it down much like a Traxxas vehicle. Don't turn your nose up at it as it's worth looking at.
