Good GSDs come from various lines, all of which are represented on this board. More important than style, is temperament, but you can start with the style you like and then narrow that down to the temperament that you want.
There is no need to be insulting about the varieties of GSDs, or to suggest that good ones are only those that are pleasing to your eye.
Educate yourself about the various lines, and then choose the ones you like the most, or if you like a certain line, but do not like a feature common in that line, you can point at that characteristic and ask if there are breeders breeding that line more moderately. For example, I like the German Show line dogs, but am not crazy about the roached back, is anyone out there breeding dogs that are not quite so roached?
Or, I like the American Lines, but do not want extreme rear angulation. I am looking more for balance.
There are plenty of lines that tend to be straighter across the back, or at least their hips and withers are closer to the same distance from the ground than show line dogs, if I am interpreting your description properly. You might look at DDR dogs or Czech dogs, which tend to have dogs in the color and style you seem to prefer.
Google Linda Shaw, she has a pretty good definition and pictures of the various lines.
GSDs are found in lots of countries, you might find it cheaper and easier to import from somewhere closer to you than the US.
