The 3 most popular electric TC's at my track are the TC3, Losi Triple X-S, and Schumacher Mission. The occasional 4-Tec can be found. I am the only guy running a Tamiya, but I just got a TC3 a couple of weeks ago. I traded some old computer equipment for it with one of the guys at the track. Getting used stuff from the "hardcore" guys at the track is a great way to save money. TC3 "team" versions have sold for a little over $100 (rolling chassis). Radios and ESC's can be had for a fraction of their original cost. And the racers take care of their stuff, so it's just as good as new, and not as risky as eBay because you can see it b4 you buy it.
