I'd really encourage you to look into flying clubs. They would be perfect for you, especially as you get back into flying and you would like access to different airplanes as your experience and inclination grows, without the day to day personal commitment of time necessary to just keep the airplane airworthy, whether you fly it or not.
There are so many clubs available that you can pick and chose one that fits your needs precisely. Most have an initial buy in and relatively modest monthly dues. They will have a variety of planes from one or two to a small fleet. You get access to the club's planes at a set price per hour which covers the club's actual cost of that plane. You can put time in at the club or walk away at the end of the flight, whichever is your inclination. If you don't use the club for a while you're into it for nothing more than the monthly dues.
I think you'd like that a lot better than getting into one plane now and running the risk of outgrowing it in a couple of years when you want to fly your son and some friends someplace warm for a spring break vacation.
