that question you pose is a very dangerous one, you are gonna get 400 different opinions.
I suggest a nice flyer like the 4 star as suggested but also might want to consider:
1. Ultra Stick 40 or 60 size
2. Seagull PC-9
3. Hanger 9 Cherokee
like Dennis states ther are numerous "sport" planes out there, I stat the ones I did becuase I have had them or fly them currently and they are very nice planes.
On a side note I loved my 2nd plane so much that I lost last year I found a used one recently and bought just becuase

it was my first low wing plane and it flew like it was on rails. It was the Hobbico SkyVista.
good luck and enjoy
pm me or post here if you have other questions
