Major O/H cycle is 8k hours. In 20+ years of almost daily involvement, I've only seen two sets of P&W overhauls. Both were optional rather than mandatory because the owners wanted to do them, neither provided squat in terms of reliability or performance.
Not necessarily, depends how much you fly, works both ways as well. If you don't fly much and never intend to end life your engines you can actually get really cheap calculations due to the relatively low cost of keeping them in tune until you're done. A recip cabin twin only makes sense as a family plane or such. When business class dispatch reliability is required, so is a turbine. It is possible to maintain turbine like dispatch reliability but the cost will run similar to operating a turbine, you just spend less money more often with the recip. The real reason that turbines are tricky is that $250,000+ engine repair hit. As a private plane, you eat that. As a business asset you deduct it at least.
