Allison, I wanted to continue my education with GUE. I believed that I would get a more rigorous and demanding class (and I did) and it would remain consistent with what I had already learned (which it did). It was only after having done the other class that I began to compare the two and ask myself whether the difference in cost was really reasonable.
But honestly, there comes a point in many things where it's hard to justify the increase in cost. A Timex tells time; a Rolex is much more expensive, and tells time; a Patek Philippe watch is insanely expensive, and tells time. Obviously, there are qualities other than timekeeping that cause people to decide to spend the money on the expensive models. I think that's true with GUE classes as well -- you DO get excellent and demanding instruction, no question about it. You're not going to get passed out of a GUE class with the kind of behavior that Cave Diver is bemoaning on the WTF thread. And it's very hard for me to evaluate my other class, because I'd already TAKEN Cave 2, so I had a bunch of information and practice over the topics already. Same with Peter -- he took a MUCH less intense Full Cave class, but he's done all his subsequent diving with highly trained people.
Five years down the line, it may matter a lot more who you dive with, and less who you took your classes from. I don't know.
