I agree with the above poster, stay away from the above schools, and let me list a couple more.
Stay away from:
Chandler Air Service (CHD) - Bad news all around.
CRM Airline Training Center (SDL) - Just lost part of their FAA certifications, and are on the brink of going out of business - owner is more interested in running his Citation Type Rating program then actually running a school - very poorly managed and ran.
Sawyer Aviation (SDL) - Bad news all around. From maintenance to management. I had a Examiner refuse to do a checkride with me because I was going to do it in one of their airplanes. Figure that out.
Pan Am / Westwind (DVT) - Been beat to death enough on this board, however from the students I know that have gone to Westwind, it isn't much different then Pan Am.
Any school out at Glendale Airport (GEU)
The above lists are not skeptical, I know either students or instructors that have worked/trained at each, and have first hand experience of what goes on there.
I would recommend try ATP out at Gateway (IwA), Mesa Air Pilot Development (IWA), or Executive Aviation at Falcon Field (FFZ).
But thats just my .02, be sure and research and get unbiased opinions about every school you consider, and be sure and ask all the right questions.
