+1 for the Spec-R I have an S1 and 2 R1 Pro Specs and they are awesome bang for the buck. The 3 Racing Xi Sports is not a bad car either, maybe a little more fragile than the S1 from my experience with club guys who drive them, they seem to break more than I do, but that could just be drivers. The older Sakura Zero is a beast though and just as indestructible as the S1.
