Private Pilot's License (Aircraft)

I have a license with an Instrument Rating and about 500 hours flight time. However, I gave it up many years ago. It's a lot of fun to fly, but very expensive. I previously owned
3 different airplanes but the costs of owning are ridiculous. Anything that has 'airplane' attached to it is going to cost you money.

What kind of planes did you own? Were you into twins at all?
