Yes Bigdood, I've been trawling through the shops looking at every make and model that I could find. In the price range that Vauen and Design Berlin sit in I was partial to the designs, grains and finishes of Design Berlin.
As for smoking quality of either of the two brands I haven't any experience and also, as stated, I have an slightly irrational bias against Vauen due to their market dominance. I asked if you had seen the Design Berlin models merely out of curiosity and am not trying to persuade you either way on what you buy. In reality the Vauen pipes look good.
I did buy a Passatore pipe for my first purchase and can say that it is a great pipe at a decent price, smokes well and is comfortable. It is Italian and not German though (not sure if you are set on buying a German pipe).
