My first sewing machine was a Dial N Sew and I still have it. It doesn't have cams, but it has a dial on it and does a few stitches such as ZZ, blanket stitch, etc. I got it new from a door to door salesman I believe in 1979, but could have been 1980. It still works well and when I went to a sewing machine repair shop to purchase a walking foot a few years ago the owner said they were very good machines. I have never had it worked on, but have maintained it myself. I haven't used it for over a year now as I have gotten a couple of old Italian Necchi's that I just love.
