Out of all of the big schools, ATP seems to do a decent job of entry-level training without ripping you off.

But before you relocate to one of their facilities, do check your local FBO's...if you can live at home, do your training, and get a cfi job at the local patch that may be a better option. You have to be careful, there are a few great FBO's/local schools and a whole bunch of not-so-great ones.
