+1 for Executive Flyers at BED or LWM. Top notch instructors, and management. Yes, they can be a bit more expensive, but you do get what you pay for.

Stay away from Horizon, the person running that place is a real first class a-hole. I speak from experience.

I would say I'm somewhat indifferent to East Coast Aero Club. I know some people there, and it's not a bad place, good management. The big drawback to there is that it's not a 141 accredited school, and the vast majority of the CFIs there only work on a part time basis.
