Just finished learning how to fix dents using paintless dent repair method with the Ding King. I learned more than I thought I would. It wasn't as difficult as I thought it would be. The guys there were very helpful. They spent a lot of time with me helping me understand how to access various panels and how to tell the when a dent was completely fixed. If you want to learn PDR, you should really consider the Ding King. I'd highly recommend them.
