Bloodrush, It depends on how you define cheap but if your going to spend in the 220-240 range you cannot beat the regular RB S7 (not the WS7III). If your track is short then even a RB S5 will be good. Just make sure you have the right pipe (RB 2020 or RB 2045). These are very reliable, have good power and they last. The fastest motor will only make you faster in a striaght line but often will make you slower overall if your not up to using all the power (many people are not).

Inferno777 remember this car is still new compaired to the others, look how many revisions both the Mugen & Kyosho have already had to them over the last couple of years. I switch from Mugen & do not regret it. I will say that the Mugen "R" that my buddy is running now handles much better than my pro-spec did.
