I can't comment much on the tipping of the DM, as my OW class was a 1:1 with the instructor due to his inability to find other interested students in October in Maine. I will say, however, that even though I paid him for his time, I felt the class was so worthwhile and he did such a great job that I ended up tipping him in the form of a thank you gift (diving related, of course!) for everything he did. Not saying this is the way to go, either, but I felt it was a necessary gesture in my case.
