It has been interesting to read the wrangling between Bob and Brendon. I know Bob, and I'd pay $400 for his class in a heartbeat. I don't know Brendon, but apparently people feel his is worth $1000.
I am, I think, a reasonably affluent person as a diver, and I have thrown an awful lot of money at this sport. But two years ago, I had to choose between two classes at the same level. There were definitely going to be differences in the amount of material covered, and quite possibly differences in the standards to which students were held. Both instructors had very good reputations and were known to me personally. I had a strong personal bias toward one class, but it was THREE TIMES the cost of the other (and neither was cheap). I really had to sit back and do an "it's better, but is it three times better?" analysis for myself, and I took the less expensive class.
If you're going to price yourself wildly out of the mainstream, you're going to have to do an awfully good job of selling yourself -- because even someone like me, who isn't averse to spending money and who understands the differences between one class and another, is going to have a breaking point where better is the enemy of good.
