A big problem with turbines is overhauls and how they are calculated. For piston engines, overhaul time is calculated from amount of hours operated. For turbine engines it is calculated from amount of hours and amount of start-stop cycles, whichever is reached first. And in GA, you have short flights and many cycles, which results in overhauls being much more common and expensive.
