Why do you want to fly piston?
Do you want to live?
Pistons are a lot slower and cheaper. It'll be easier trusting a guy in a 50k airplane than a 500k airplane. You have to learn the basics first. After a year or two you will move up. Yu will get more flight hours in a piston because it takes longer to do the job. Not to mention insurancing a guy I. A cheaper aircraft.
If your mind is set on owning your own operation find a fellow trying to get out and start working for him with the goal of buying him out.
