I flown the Robin DR 400, not bad I must say. Cracking view out of it. I am just not keen on the flimsy skin of the aircraft. Also I would not say it is ideal for a trainer. The hand break takes some getting used to as well.
The Grumman AA5-B is not bad either. After the PA32 I fly this more than Cessna or Piper. It is quiet a skitish aricraft though, yet I find it the eastiest aircraft I have flown to land. you just need to be careful of the flimsy castoring nose wheel. Again probably not the best trainer.
