We have had our 150 for a little over 10 years. Our cost is close to Bruce's. With hangar rent, annuals, maintenance, fuel and everything, our cost is about $5,000 a year, or pretty close to $400/month. I usually fly between 50 and 65 hours a year, year-in year-out. And, you are right about renting. Most people won't fly as much.
