sassgrunt, be careful with the plastic sides on the Asiatam hull. It's prone to cracking from overtightened screws and I just noticed a crack where the idler is. Not to pleased about this, but it's not noticable and has not affected performance in any way. Also, the idlers take some getting use to and can be completely unscrewed without you noticing until the tracks are really loose after you hit something with the idler wheels.

I paid $250 + $14 shipping for mine from RCCommand.
