Looks like you may be going at this by yourself for the most part. I would recommend against the Super Cub. In my opinion and from experience trying to teach new pilots who went and bought them , the plane is not a good first plane. Yes it repairs easily and therein lies the rub. You WILL be throwing money at it as you crash it or rough land it as the parts don't hold up that well. prop shaft, gear box, cowl, etc... After awhile it adds up.
I would stick with your initial pick or one like it as you will get much more mileage out of that type of plane with less money thrown at it to keep it airworthy and then you can move up to a larger plane like the Apprentice 15 or similar.
