Michael,
If you're set on doing your training at Parafield, I'd recommend also checking out Forsyth Aviation..
Whilst Forsyth might not have the vast fleet and flashy brochures of FTA/AFTC, I'd argue that you will get a much more personal experience from Forsyth's. Whilst I didn't train at Forsyth's, my experience dealing with the staff there for private hire was always positive. They've also got a few nice newer 172's and a 182. In hindsight, I wish I did train there.
Whilst there are some good people at AFTC/FTA, it is the proverbial sausage factory. Your booking will get bumped if an FTA student needs to use the aircraft (not saying thats wrong, but you have to remember that the number 1 priority of that organisation is to train the cadets for the various airlines they have contracts with!). And AFTC has a high turnover of instructors as they gain the experience to move to FTA, so expect to change instructors at regular intervals (every 2 to 3 months).
If you have any questions, PM me.
