The mom & pop shop I rent from charges $145/hr for a 172SP.
Instructor's another $45-$65/hr.
Just sayin'. I hear stories about $45/hr 172s, but I've never seen it. Cost of fuel + % of overhaul alone is significantly higher than that.
So $100/hr dual for a 172SP doesn't sound like a bad deal to me! For that matter, my seminole time at ATP was just over $300/hr dual... for a brand new seminole in pretty great shape. It came with all the sim time I could eat, free written tests, and some other goodies. Never did get a shirt, though. :>
By comparison, the 1979 Duchess I rent is $288/hr solo.
So really, people who say that ATP is 'extremely expensive' leave me rather baffled. ATP is a -very- streamlined organization, and as you might imagine, they seem to cut costs mostly by risk management, good planning, and careful cost control... but frankly I still feel like I got a bargain doing my commercial multi there, and I'd like to think that anyone who keeps their eyes open and understands what they're getting could do much worse. I've even considered going to the SAC ATP to do an IPC, since I'm coming up on it. I probably won't, but I wouldn't even consider it if I felt that they didn't have value.

PS. I really like the place I rent, so don't get me wrong. They're not the most expensive in the area, by far ... though not the cheapest, either.
