The Cap 232 you linked to is a nice setup with a DA-50 for power. However, its a large stepup from the trainer your now flying.

A good second airplane would be something like an Ugly Stik still high wing airplane capable of doing some nice aerobatics. A lot of pilots keep a Stik in their hanger as good utility flier for windy days and knocking around its fun to fly. The Cap could possibly be a good follow on airplane from the Stik.

Good luck with your quest there are a lot of nice airplanes to choose from.
