I think she meant 31-15 when she was talking about industrials. I have one, but I haven't used it much, so I can't comment on how well it quilts.

Parts for the 31-15 are generally super easy to come by and fairly cheap.

My favorite quilting machine is my 15-91 - lots of room under the arm, big bobbin vertically oriented, droppable feed dogs and very forgiving as far as balanced tensions go. I regularly quilt large quilts on it - queen and king size.

I also have a Singer 28, 27, 127, 66, 201, 301, 316, 401, 403, 500 and 503, but my favorite quilting machine for large quilts are my 15's.
