Does anyone have a breeder they would suggest to the guy. I don't know that he asked to be dissuaded from getting a puppy. He feels it is the right time for he and his girlfriend. Using the dog as part of the engagement, is maybe what some of you hiccupped on, I am guessing.
jwjames, I am in Ohio, and do not know of any breeders I would be willing to locate where you are. But MRL's advice is good. There are no short cuts when it comes to finding the right breeder for you. There's a thread on now about a person unhappy with a breeder that was suggested on here. Maybe a couple. Someone will give you names of course, but from what you said, you need more information before you start your search in earnest.
You need to educate yourself on the different lines of GSDs. There are the American Show lines, German Show lines, West German Working lines, Czech lines, East German or DDR lines, and maybe others. Each has its strengths and weaknesses, and some of them may be a better match for you than others. Linda Shaw has a pretty good synopsis of the various lines, and it is well worth the read.
After you and your girlfriend determine which lines suit your situation best, then you need to go through all the stuff about how to find a good breeder. You have to decide how much you are willing to pay and what you will require in the puppy you buy. Even though you do not want a dog to show or work, the temperament of the dog is of the utmost importance. When you do narrow down what you want and start seriously looking at breeders, be very clear about what you want the dog for and what you are looking for in the dog, etc, so they can match you up well.
The following gives a synopsis of the different lines, with photos:
