My 18 year old Bernina 1031 gives me no problems sewing over pins. I'd highly recommend a vintage Bernina mechanical (not a computerized) machine. They are truly workhorses, sew those heavy seams, are still made in Europe, and do not require you to buy expensive feet if you find one with all its parts and don't need it for specialized sewing. My current 18 year old machine finally went in for cleaning and routine maintenance after 8 years just because I was going to spend a week in the area where the best repair person worked! It was fine before and it's still fine now.
