I would say go with a XXXNT or RC10 GT, like X said you want to be sure you can get replacement parts and after market support easily. Old RCs that you have no idea how they were broken in, run, or taken care of can cause you more misery than enjoyment, especially if you have to look forever to find a part for it. In many cases it will cost as much to get an old car to running well as to just buying a good quality new car that you know how it is broken in, taken care of, and how it is used. Too many surprises with an old used RC.
