Anyone have any experience with Bill Hillman's DVD's? I'm looking at the "Training a Retriever Puppy" DVD, but I don't want to spend $129 if his program doesn't work. Trained my last lab with Fowl Dogs I and II and Chris Akin's Duck Dog Basics. I was generally happy with the results, but I'm always looking for more/better training methods. If anyone has any other recommendations, I'd appreciate those too.
