I've seen the Guyer clipping video, the selection video, and the daily care video. They're just as good, if not better than, the Stierwalt videos. The Guyer videos seems to give all of the same details that the Stierwalt videos, but the Guyer videos seem to have more depth and are more cutting edge. I'll note that I have my clipping DVD on eBay for 42.99 plus (I think) $3.00 shipping. Even thought I am trying to sell this DVD, my strong endorsement of Guyer's DVDs is genuine. Let me know if you have any more specific questions, and I'll do my best to answer.
Additionally, I talked to Kirk about whether he would be coming out with new videos, and he said that he would be. He even intends on making a feeding video, which I am looking forward to seeing.
