My 201 is heavier than a 128, a Pfaff 30 and 130 are even heavier. I think part of the reason the old cast iron machines are favorites is because they are heavy, makes them very sturdy, smooth running and capable machines. They just aren't as portable as more light weight machines. My 201 came rather randomly and I kept it. A 66 is nice though, it runs lighter than my 201.
