I used to have the Kenmore 19233 and the only reason I sold it was because I got a new machine. The problem I had with the Kenmore, and honestly not many folks will have this issue, but I was making a rag quilt, and I needed to sew thru 6 layers of flannel, and I could not get the machine to do it. But everything else I used it for, it was wonderful. You can still find them but they are getting harder and harder to find. Here is a link to Amazon, they still have a few left.
