Hello,
I just finished my CFI-A at Flight Safety two weeks ago, it was the only rating I did there. I really liked it, the instruction and facilities are first rate but I should mention that its really, really expensive. Still, I'm glad I did the rating there and I learned alot, I guess you get what you pay for. I'd highly recommend calling and setting up a tour, the best way to know if its for you is to check it out personally.

Hope that helps a bit.
