Ya, there are these kits by Yokomo that are 199.
but by the time you buy all the electronics needed (motor, remote, servos..etc) then it gets expensive.

But I still think i'm going to get this 180sx kit
looks awesome


Here they show to be expensive - http://www.yokomousa.com/kits/drift_intro.htm

but here I found them for a pretty good price (in comparison)
