Sims are the best way to practice on a regular basis. You don't even have to leave the house, especially on those rainy or excessively windy days, to have a great practice session!
I agree that not everything is perfect with the simulators, but I learned a lot of difficult 3D maneuvers with mine and practice IMAC all the time on it! I look at the sim as a way to extend the flying season! And if all you have is a few minutes, you can still get some valuable practice time in!
