what about Rotor, also a German brand, not too expensive, they sometimes have deals where you buy the bike + rack + paniers at a good price, I've seen them in action and they are quite nice! http://www.rotorbikes.com/de/bikes/reiserad

otherwise, this is a nice online german shop, they have quite a few touring frames: http://www.bike-components.de/shop/c...ng-Frames.html
