I'll agree with this. I just purchased a used Gen 1 this past Summer and everything regarding the setup thus far has been super simple.gen 1 would prolly b a lil easier to start out with, not the best car but it a lil easier than a gen 2, not as much stuff to worry bout...
Best car for the money in my opinion is the 10R5 Associated car. You can find it for $265. right here on the for sale forum, that includes everything except tires, body and electronics. And the setup in the manual and the one online is great on the track. Easiest car I've ever built.
BUUUUUTTTTT the one to get is the one that most of the guys at the track you're going to race at run. They will be able to provide hands on help for the particular chassis and you will save yourself a ton of money by going and talking to them first. Someone might even offer to sell you one of their old ones to get started at a discount price.
