Yeah I saw that d6d pop up on craigslist, first appearance it does look like a good machine, but for my purpose I really need push arms. I have had good luck with d3s and little case 6 ways but the larger ones seem to crack and rip the centers off eventually. That and hydraulic lines. I was told by a guy yesterday that a d6r frame by itself they picked up with a 10k capacity lift, so the frame for sure must weight less than that.
