The only problem with the more advanced aircraft is the hourly rate, unless money is not a consideration I would suggest learning the basics on something simple such as the Robin which is actually a reasonable aircraft for covering up to the AOPA aero's cert. and then moving onto something more advanced such as the Cap10 as you progress and then on up the ladder.. . As far as capability goes, IMHO the Robin is MUCH nicer than the C150, The Stampe is far more capable than the DH82a but will probably cost you as much to fly as a Cap 10.
