SimCom
Try SimCom in Orlando ... they have a visual, fixed KA-200 simulator, and I suspect they'd be substantially less expensive than other alternatives. Simuflite (DFW) and FSI also have 200 simulators. I don't know what any of their policies would be with regard to just using one for an hour or two versus going through one of their programs ... that'd take a phone call.
I couldn't even speculate on cost ... other than to say I believe my employer paid SimCom about $6k for my 200 initial school back in March.
Good luck.
