Pfaff 30 is a straight stitcher, perfect for the heavier jobs, a notch or two stronger than the average model 15, and the 201. My impression is that the later 15 clones are nice machines, but generally not noticeably stronger than the old Singer 15s. The Japanese made clones I get here are sometimes fitted with a UK made motor and lights. I think there must have been some sort of tax on electrical goods during the 50s that made it cheaper to import machines and set them up with motor and lights once they arrived. These motor setups are often slightly stronger, but it's difficult to generalize. Pfaff 30 has the strongest motor of these, the same for some of the old straight stitch Husqvarnas I've seen.
