Went through that myself.. I was looking at the DRX, but decided against it because it's only single-speed, and though surely fun in curves and for drifting, it won't have the speed I want. I like everything about the car except that it's sure to have a really lame top-speed..
So I got a DM-1. Haven't had a chance to run it yet though cuz it's winter...
I got the 1/7 kit(see in the DM-1 thread..) Nice quality, fun build..(it's really half built already, but still...)
I also considered the Kyosho inferno GT2, but thought they seemed crappy quality. And you need mods to sort out their apparently perpetual 2-speed problems..
For a strictly on-road kit basher, DM-1 all the way..
