Just received the Blitz aluminium cos got tattooed by an artist that was using one. Very happy with it, hard hitter, in single pass packing colour solid in and have the feeling that it bogs down a bit when in contact with skin-great!. Ill be interested if anyone has both the d 20 and the Blitz and what the differences are...? I like the blitz cos is slow (gives you enough time go over a spot without too much trauma while packing thick ink) and has solid hit. I tried a lot well known rotaries out there but settled with swashdrive and Blitz. What bothered me about the most of the rotaries I tried that they are freaking fast for colour work (anyone got the feeling too?)....
