So I rode one of these recently:

and now I want one. But I'll never use it for the trails, just bike polo/footdown/random other bike games so I don't want to pay $400 for it. Basically I'm going to get a cheap used MTB frame, take everything but the smallest chainring off and put a new rear wheel on. Does anyone know where can I get a big coaster brake mountain bike rear wheel?
