If you are looking for a buggy to bash, I'd suggest something that you can afford to fix a lot and has parts that are readily available. Bashing around on the street, parking lot, or backyard can play hell with parts. Bashing is really hard on a buggy. I'd try to avoid an RTR. RTRs usually come with crappy servos and the radios suck. Even my Mayhem RTR wound up needing new servos the first week and that was around a $500 rig.

If $350 is all you have, maybe you should wait a bit until you can afford a bit more.

Many of the RTRs will include an engine that either has a pull start or shaft starter on it. Both are a PITA as both utilize a one way bearing which will invariably go out and are not cheap. Pull starters also break regularly and are also not cheap. I'd say, start off right and go with a starter box.
