I agree, in your quest to find a long-term plane, you might buy something that's too hot and crash it.. leaving you with no plane.

I have no experience with these planes, but from what I've read, the Tigermoth, the Mini Mag, and the Estarter are good aileron trainers. But, I guess that is exactly what OZ said above. I didn't read until just now.

I'm already thinking about using the tigermoth as a trainer when I want something more challenging than the supercub.
