I've bought a couple of these over the years for my mother, a prolific quilter of 30 years. A few of her friends had them and she wanted to give one a try. The first one she bought from a friend 20 years ago, had it serviced at the Singer shop and it worked OK. It was in minty, like-new condition but gave her all sorts of trouble while using. She ended up selling it after I came across an estate sale of a sewing machine collector and bought another FW for less than $50. The house had roughly 150 sewing machines, parts, manuals, etc. By the last day of the sale, they were giving sewing machines away if you'd take them. The FW had been serviced but I cleaned it up and mom gave it another go. It seemed to work ok but she missed some of the features found on newer electronic machines (needle-down stop, etc.) and eventually went with a 3/4 size Pfaff portable and last year bought a Bernina 300 series for retreats, classes, etc. She's had Berninas since 1976 and is a loyal customer, her last 750 QE had >5 million stitches logged.
A number of her quilting friends still have FW machines, but most don't use them regularly other than for the occasional nostalgic value.
