I agree the Dachau types are more or less at the bottom of the desirability scale, but they are "legitimate" swords. For some, they are the only affordable SS officer sword. For others, they are a variant to add to their collection of other swords. They probably were awarded mostly to W-SS and other military SS officers. If you can only have one and have the funds, go for an earlier sword. However, I don't think there should be any "shame" or embarassment associated with owning a Dachau type.
