Since the T4 seems to be the most popular option:
Here's some pics of the T4. In the red box are a whole bunch of used parts as well--including a full set of shocks (from the Team instead of FT), a whole transmission, and more. Overall it's very clean and low use. It is due for a diff rebuild, and I've never gotten the wheels and tires to quite balance right. Electronics wouldn't go with it, unless you really wanted to experience old-school brushless:) BTW, the chassis on there is the carbon one, as well as the extra. Everybody else seems to prefer the plastic, but I found I liked the carbon better.
