I have limited experience with ATP, but I have to agree that if you're looking for a package-deal kind of place it seems decent (compared to the other big schools). They don't try to send non-cfi's to airlines, and they do not appear to try to rip you off in training.

My preference would still be a good mom & pop kind of place at the local patch...if one is available. You can meet all kinds of people at a place like that.
