Since you've been to shows, you may want to contact those breeders. From what you're saying - with the lower prey drive and coloring, it sounds more like the showline kind that you are interested in. While you waiting for replies, you can look on the AKC site under GSDs for breeders and a club contact in your area that can help you. There are also helpful threads here on what to look for in a breeder. You may also want to consider rescue.
