I have the Tamiya A4 STW kit..it's a great chassis-the TA-03, I think. The best part is that their whole range of bodies will fit it. I'm sure they will come out with a TT body soon, if they haven't yet. I wouldn't be surprised to see S3/4/6 bodies either. They already have an R8R kit out, and I think it uses the same chassis.
