Switch Blade,
Not trying to butt heads but ntc is trying to narrow his choices not broden them and in turn making the choice harder.
Ntc,
Your choice is going to depend on how much you want to spend. I just bought the Jammin and it rocks. I decide on the Jammin because it is almost $200 cheaper than the 777 SP2 and the MBX5, and spare parts are cheap also. The Jammin is super tough and its keeps up with the high end race buggies. Read the latest Xtreme R/C Buggy Cage match, the Jammin came in second to the Kyosho SP1.
