Specific Attributes of American and Eropean Dobermans

Hi! I'm new to this site, and am currently in the research process of obtaining my Doberman. I have several questions that I need help with. First ( and I realize the amount of ignorance this will reveal) I was curious about the differences between American Dobes and Europeans? Not only the physical attributes , but also the emotional aspect attributes as well as cost, access to breeders and health risk (if there is any difference between the two). I am currently a student at Montana State University, and I have not enter the decision to get a doberman lightly. I have wanted one since I was young and the desire has only grown with time. I have looked a two breeder in MT and I would really appreciate it if anyone has any info about them.
