My wife has a newer model. But, last summer I picked up an old (low numbered) White 628 Zig Zag (heavy Duty) for free. A university student was throwing it out, says it was her grandmothers and it did not work. I took it to a repair shop, cost me $35 for a tune up-nothing wrong with it is like new. In refinished the cabinet. It is a really nice working and pretty machine-white and mauve in colour.
