You might also consider a Dynavector 17D mkII - same price range as the Benz L2. Hard to lose with either, both are fine cartridges, and I have heard both sounding good with a Spacearm/Spacedeck. Same guy that had this combo mentioned that he preferred both these cartrdiges over the Shelter 501 though his friend preferred the sound of the Shelter, while he preferred the sound of the Dynavector. In both cases, the Benz was the second choice.
I have a 17DmkII and really like it, for what that's all worth...
