I run a Tamiya 104W. It's the Maclaren Mercedes kit. I installed an aluminum diff and motor mount. I'm also running a 1.3 mm t-plate. The tires that come with it are hard. Pretty much everyone runs Pardous tires. The friction shock is worthless so I installed a shock from my TC5. So grand total you are looking at about $260 for a rolling chassis. I know Phil at Eclispe Hobbies has been making some package deals so you might want to talk to him.
