I just did my IR and CPL with Cirrus Aviation in Sarasota. They were very good; superb instructors, and a decent fleet; 4 Cessnas and an Arrow. Couldn't recommend them enough, and Sarasota is a lovely place to stay!
I have also flown with a slightly bigger outfit in Camarillo, California. Channel Islands Aviation; a slightly larger, Cessna fleet. I flew with 2 of their instructors, both were superb.
Both of these schools are family owned and run!
