You might want to rethink your requirement that your first plane allow you to move on to aerobatics, especially if you're trying to go it alone. A plane suitable for aerobatics is going to be far too responsive and neutrally stable for someone who has not yet developed the proper reflexes for flying airplanes. A plane that is less responsive and more positively stable (i.e. it tries to right itself when you let go of the sticks) is much more suitable.
