Since you mention that, Ken, I'll run with it for a moment if I may.
I am a PADI and SDI instructor. I don't really care which one I teach, they are all just alphabet soup and each is as crappy as the other. I tried to teach a DM crossover the other day. It was important to cross the DM to SDI so that they could go on to be a TDI DM for tech liability insurance. I have dived with the DM candidate, he is a PADI DM in good standing, he meets the requirements to be a SDI DM with some tests and skills tests. Imagine my surprise when I couldn't set the price to do a crossover for him. The only way to do the DM course was to sign up for the online course. I, of course, weasled my way around the online course rules, bought him the books and test and required falderol, and completed his crossover.
Where do the training agencies get off telling me how much to charge for a course? I'm considering not renewing, but that doesn't really gain me anything. The training agencies are going the way of the manufacturers in price setting. I'm not happy.
