All the schools have their good points and their bad points. Everybody will give you their opinion based o where they learnd/work so it will be a bit biased. The best thing to do is ring them all, or drop in and say hello and ask a few questions and then go somewhere you feel comfortable.
Here are all the schools in no particular order;
Aero Club
Air Australia
Aviation Institute of Australia
Minovation
Jandakot Flight Centre
The Aeroplane Company
Sorry if I missed anybody out.
