It sounds to me like you have your mind made up on where you are getting your dog.
I mentioned breeding because, while intact, this dog sired a few litters and a few turned out to have mega esophagus, and at the request of the owner, was not to be a stud.
If you are asking for opinions on where to get quality imports, I can only point you to where I got mine: Von Falkenhein AK9 Breeder (German Shepherd Breeder German Shepherd Puppies
I wanted to do all the training and titling myself and didn't care for a fully trained GSD and, instead, went for a pup which I got from AK9. They also sell fully trained K9 imports too. ->
