Citab's pretty easy, too. You can even see where you're going when taxying, as it's quite nose-low for a tail dragger.
Cub or Chippy, I'd suggest. Preferably a J3 / L4 rather than Super Cub as they are flown from the back seat and are therefore more demanding to handle on the ground. Also the lightweight 'little' Cub is 'closer' to a Turb.
