Sorry I've been away, but with some serious family problems lately, I still feel my time was better spent away from ScubaBoard.
I think I'm a fairly average instructor in SEI. Maybe slightly above average, maybe not. SEI has some really outstanding instructors. I wish I had the time to go audit their classes. I'm sure I'd be a much better instructor as a result. SEI may or may not be the best, but I do believe it's in the running.
Sorry to hear about your family issues, hope it all works out.
