I second MSUSpartans on Pan Am. I also wouldn't recommend Westwind either. Out of the two I'd pick Westwind, but it's all the same no matter how you look at it, and will cost you much, much more money then you would've normally spent otherwise!
I did all my flight training in Phoenix, and know someone that has attended or taught at almost all the flight schools there.
As for "Academy" type programs:
My first recommendation would be the Mesa Air Pilot Development (MAPD) at Williams Gateway (IWA), followed up by All ATP also at Gateway.
As for "Mom and Pop" type schools:
At the top of my list, hands down would be Falcon Aviation at Falcon Field (FFZ). They have an impressive cross-cut of airplanes, and their maintenance is second to none in the Valley. Always friendly and helpful, they make you feel welcome from the first time you go in. They are the only ones that I would rent airplanes from when I wanted to go up and do some personal flying. Also did my Commercial training in their Piper Arrow, so I can atest to their training program, and quality of aircraft.
I would also recommend you check out Angel Air at Stellar Airpark (P19). I say "mom and pop" but they are very professional, and offer high quality training, and have mostly all new 172's in their training fleet. First class orginization.
Definitely stay away from Chandler Air Services (CHD), Sawyer Aviation (SDL), any flight school out at Glendale (GEU), and Crew Resource Management (SDL).
There is normally a couple more schools I'd recommend, but I just found out from a phone call yesterday that they're both in financial trouble, so I would be hesitant to recommend them.
Good luck searching, and let us know what you find!
