Searching German guns by brand will really steer you away from some of the best deals out there. There are many guns without brand names, which often are referred to as guild guns. They as just as good as those names you have mentioned. You need to look at enough of these guns to discern which are good (most) and which are wasted. Great no names often go for a fraction of price of brand name guns of same quality or even better. Take the time to learn to read German proof marks and to develop an appreciation for fit and finish. Also the deep relief engraving you seem to like is usually an Austrian gun not German.
