I still think workshops are great - if they're small.
I recently signed up for another workshop next January, and am really looking forward to it. As for myself, I prefer the "hands-on" of "change this setting, move this strobe here, try this, etc.". Yes, a smaller workshop costs more, but in my mind that is exactly what I want. I find telling me to do something and SHOWING me are both very important. The lectures only go so far. Some "in pool" time to show me stuff, as well as in-water and on-boat, are exactly what I'm after. And after trying to get in this guy's workshop for a year, I finally snagged a spot!
