Crew costs? That makes no sense to me. There is a fractional Pilatus operator thats seems to be doing fine. They pay pretty well, better than NJA till recently. Saying "cheap airplanes don't work because you need to pay pilots" doesn't make any sense to me.
After you pay the pilots you are still left with an airplane that is cheaper to purchase and cheaper to operate. And if that airplane fits your intended mission then you can't do better than that.
