I've imported a bunch of Dobermans from Europe. Based on my personal experience, I agree with Kansa. Forget about the quality of the dog, or even the price, but how do you expect to develope a proper relationship with a person who can't speak English? Or does so very poorly.
A lot of people (noobs and pet people) get enamored by the "look" of european dogs without realizing often this "look" is achieved simply by the style of presentation. The differences between Dobes in Europe and Dobes in North America are very subtle, in person you wouldn't be able to pick them out, unless you are a very serious Doberman person.
For the great majority of people, I see no reason to buy a dog from Europe. All of the reasons you *think* are why you want a European dog are wrong. Whether it's temperament, structure, w/e. The simply best and smartest thing you can do, almost unequivocally, is to buy a dog from somone locally, who you have a rapport with, and will help you select the right dog for your situation.
However, serious American breeders are a bit ridiculous with all the stipulations and how difficult they actually make it to get a good dog.
