Go to a club meeting, try some cars on for size (might cost you a beer).
Then make a list of what you want in the car.
Ie : Looks, Ability, Ease of assy, removable body, independent rear end, wheel dish, engine choice, fuel choice (these 2 can be thought about together, as LPG can be fitted with different engines), gearbox choice.

And as mentioned the term "roller" means alot of different things, so just exactly what do you refer to as a roller?

Another option is that I dont know what your time line for "needing" a car or kit in the garage, but the Nationals are comming around pretty fast (late Sept early Oct), so it may be worth making the trip to Goulburn, as you will not see a larger gathering of all the different supplier options than at that place.
