How about some practical experience? I bought an old C-150 with a partner way back in the 1970's. Cost about $4500 total and we split all the costs. We both used it to get our private licenses then flew it another year, when we upgraded to a Cardinal.
Sold it to buy the other airplane and after both of us flew it all this time we ended up making $500 on the plane. It was one of the best investments I have ever made and would strongly suggest that you look into the same thing.
First thing I would do is to look around your area for a plane at an airport near you, then go on the internet. Talk to the owner and mechanic of the plane. It would be nice if its near its annual time so you could look at the plane with the covers pulled as well it would have a fresh inspection during the purchase.
Just like a 911, the more past history it has, the better. Go to the FAA and get a copy of the history of the plane on CD, and research it. It costs $6 or so and takes a week. If you need help, email me. I help even liberals with airplanes!
If you cannot find something local, then look on the internet but be VERY careful. Check

If you are interested, I have a very old friend who owns a C-152 that will be for sale shortly. I flew this airplane back in the 1980's when it was used for a flight school plane, then sold to a private party. Its very low time as its been sitting for several years when the owner slowed down on flying. Located in Prescott Arizona, it needs an annual and new radio but otherwise is in good condition. Do not know anymore of the details of the plane but email or PM me if interested.
I have flown most of the light planes and prefer the Cessna to the Pipers. The high wing hurts on overhead visibility but is excellent looking down. The low wing planes are exactly opposite. My issue is that the Piper flies like a truck, with heavy controls, while the Cessna is more like our 911's with light and very responsive controls. Try both and see which one you like.
