I took the DX9100 operations & Troubleshooting and the DX9100 Engineering classes several years ago. Ronnie Auvil taught both classes. He's a pretty sharp guy. I bought the book shown in the link, but I did not pay 150. My advice: Google the ISBN numbers, and you will probably find used copies available at much cheaper prices. I think mine ran me about 60 bucks.
