Yes, I have two of them. They were Singer's first attempt at a ZZ for home use. They use the 206 X 13 needle, and like the 306/319/320 must be tipped back to change bobbins. The needle plate must be changed when switching from straight to ZZ stitching. They are quite heavy and are best in a cabinet.
They sew great (of course) and are fairly simple. The drawbacks are the needle and bobbin changing system.
As for the "industrial" listing, I have heard that the 306/319 machines are "light industrial", but have a feeling that is going more on looks that actual usage.
