I'm also shopping for schools and have considered North American. My CFI went there and has very positive comments, even about the included housing. Here's what I gleaned from a phone conversation with them
(assuming you have a PPL):
Advanced Professional Program $26,000
5-7 months (this is accurate per my CFI)
Comm, Inst, Multi, CFI, CFII
Housing included, on-airport apartments 2BR/2BA, 2 guys to a room. Fully furnished right down to the plates and silverware. They use a Jeppesen syllabus & materials, class size 40, current school size ~120, ~225 hours total time at school (15 ME). They currently have 38 aircraft, 30 CFIs. No charge to audit PPL ground school. Located at Conway-Horry County Airport (HYW) one runway 4400' uncontrolled.
The price is very nice. I had intended to go to Flightsafety, but don't feel comfortable spending that kind of money. The NAIA program is lean on multi time, but with the $30,000 I save not going to FSI I can probably find another way to build multi time. Check back here in a week-I am going to visit the school this Friday (I live 3hrs away) and can report back what I find.
