I would not buy an Xray for bashing. They are great RACE rigs....but to be honest parts are too expensive to risk while bashing. Very Very durable rig....but very pricey to fix and almost no one stocks parts locally. A-Main carries everything....but it's a few days away.
I personally love the Hot Bodies stuff these days. It's fast, durable, and parts are CHEAP.
If you're gonna bash though, find out what your local stores carry for parts and go with a brand they support. When you bash...you break stuff almost every time you go out ;-) Well...if you bash the right way anyway! hehe
