Cant help you in MI but when I was in CA I got connected with a guy who was selling a steerman for an out of state client. Needless to say the airplane needed to be operated to keep it "fresh" so I ended up flying that around for close to 50 hours over a year.

You wont find a much cooler high performance tailwheel.

Your next bet will be if you can find a Maule or Husky or Cessna 180.

Bonus points for Cessna 195 or Beaver.

Double bonus points for complex and high performance such as a temco swift or a dc3.
