Just to add some perspective, but not entirely disagreeing
Youll pay $300 plus per hour dual for a clapped out 1970s cessna or piper. If you do find a school with modern machines, you'll need every penny of your train driver salary.
The Aero Club I fly out of (GA) rents out their Cessna 172SP for $279 inc. GST wet, and this is a 2010 model, Garmin G1000. They have two Glass, two traditional gauges, all newer than 2000. Yes the Dual rate is higher, but once you have the RPL, or PPL, it is a little more reasonable(ish).
Not all operators or organisations are still flogging 30+ year old airframes, but yes, it is still expensive.
