Since Mike Ridgway is leaning his classes more and more that way, and I'm taking his classes, I guess I'm already getting the GUEF course. I really wouldn't see any need to take a course from someone else if Mike was doing the classes. To me, he's an excellent mix of toughness and supportiveness. I feel confidant that he won't pass me in a course that I am not doing satisfactorily. At the same time, he's never shown up with an attitude towards anyone.
As far as equipment, mine is already DIR. I have already moved in that direction and then got the "Doing it Right: The Fundamentals of Better Diving" book by JJ and I'd let George freakin Ervine III hisself go over my stuff now.
