Good training isn't cheap, in any arena. Example, a half day beginner outdoor photography class @ REI is $85. Basically, shutter, aperture, DoF, light, done (a good beginners glass). Full day classes from good well established teachers go from about $495/ day or so. When you go to people who have established an expertise in a subject that others want to learn, you should expect to pay them for their efforts. If they aren't any good, and their class isn't worth it, their classes will be short lived, I rarely walk away from a class and think that I did not get my moneys worth from it.
