It depends on what kind of deal you can get for it. I don't know of any places that still have the v2R, it was a limited edition kit. I got mine for about $40 more than the Pro, which is extremely good value as you'd pay more than that just for the aluminium shocks.

As for brushless and lipo, yes it can handle it. The M03 and regular M05 need rounded sport lipo packs, but the M05 v2 variants can take standard rectangular ones. For brushless motors, most people use a 21.5T sensored motor (17.5 would probably work too), or a 3000kV sensorless system such as the Hobbywing 13T ezRun combo. I'd recommend the ezRun if you're not racing at a track that specifies what you can run.
