Surprised it has not happened by now. Other options are all compromises. Aeroworx B200 ports poorly into FSX SP2/Accel, as it loses systems functionality on top of a bunch of gauge issues. ISDT is a nice model but the default B350 VC is not my cup of tea and as a result I mostly fly the (now defunct) AFG B300, which though not native, has the nicest looking VC, IMHO, currently available (swapped in a couple of payware gauges) and flies and looks fine in FSX. I even went so far as to merge the Turbine Duke VC into the ISDT King Air but for some reason it didn't agree with the air.cfg and the engines wanted to die after a a few minutes. Glad Carenado is doing the C90 (can't have enough noisy turboprops!) but that is a quite different bird than the B200.
