Yes, I have Erik Strickland's DVD and I recommend it; I also had the opportunity to attend a two-day grooming seminar that my local breed club hosted--and he was excellent.
In the DVD, Erik goes over the standard, and goes over each part of the dog; ears, neck, paws, tail, feathering--you really need excellent equipment in order to take advantage of his technique because he really sculpts the feet and ears--it is amazing to see in person, and it is incredible to push yourself to do.
In the actual seminar, Erik will evaluate dogs as per the standard, and provide guidance on how to groom so that your dog's features are enhanced according to the standard. He also shows you that unless you really think about the standard, and how your dog compares to it, you are going to have a difficult roadmap when you groom your dog. His opinion is that the golden standard is rather murky (hence, all the different "styles" you see in goldens--different headpieces, etc.)
He sells a great set of grooming shears--I've heard from some of the people who bought a set were very, very happy--said they are among, or the best pair of scissors they've every owned. I had bought a set because I really needed a new set, and didn't know any better. I have a group of friends who didn't buy his scissors and one friend has borrowed mine for the past month--they are now all going to order from him. Hope this all helps.
