Fast!, durable!, offroad!, brushless!, cheap?

[Rebelgium]

What would be cheapest?
- Buy a roller on the bay, buy a RCM motor mount, buy a motor and ESC on the bay.
- Buy a converted roller (with motor mounts and battery trays already on it) on the bay.
- Buy a RTR converted truggy on the bay.

Or is there no option that will be cheaper than another most of the time?

Also,
Could someone please give a top 5 of the best truggy's around? Don't care about the price too much, what I meant with "cheap" is the best bang for the buck. I'm still willing to spend 500$ or so...

And with the best 5 truggy's I mean the most durable, the most durable drivetrain, sturdy, ... So I can run(read: bash) a great powerplant like the MMM 2200 combo, without worrying about the drivetrain or the rest of the parts breaking.

thanks!
