Huntsmith DVD's

[Kory]

I was looking at the Huntsmith website today and have the book on the way but I was wondering what everyone thought of the DVD's

Puppy Development I
Puppy Development II
The Silent Command System of Dog Training
Training Gun Dogs Vol. 1
Training Gundogs to Retrieve Vol. 2

Which are a must have and which if any just cover info that is provided in one of the others.

Thanks in advance for any info
