Thanks for all of the great feeback. As I got only one specific recommendation for a school (ProDive in Ft. Lauderdale) I will assume that, if there is a "Harvard" of diving schools, that is it.
As for certifying agencies, I know nothing of SSI or NAUI. When I earned my basic open water card back in 1978, the YMCA training was rigerous, sometimes rough, and took a full 12 weeks to get through. I knew other would be divers who earned PADI certification at about the same time and never felt sufficiently comfortable with their skills to ever dive again after their open water check-out dive.
I got Advanced Open Water, NITROX, Rescue, Cavern, Deep, Wreck, and DPV all from PADI and all from the same instructor, Richard Rydell. Richard was also my instructor for IANTD advanced NITROX and Normoxic Trimix. These courses were all great but I attribute that more to Rydell than the course materials or orginazational philosophies both of which he occasionally disrespected and supplemented with the Rydell philosophy.
There are only two reasons that I am presently considering breaking this past habit and going to an established school. The first, is a desire to become exposed to different instructors in order to benefit from a variety of experiences, teaching methods and philosophies. The second is my desire to have an intensive, concentrated course. Doing DM with Richard would likely streach out over several months as opposed to two weeks at a school. I do understand, as some of you pointed out, that becomming a GOOD DM will probably require months of experience acting in that capacity after I get the card.
For better or worse, ProDive was the outfit I had tentitively selected for this training. If I don't get additional strong opinions on the subject in the next week or two, I will probably go agead and sign up for their August 11 DM course.
