I have 2. The first one Igot in the early 80s . It was made by simplicity, just basic. It is a workhorse still going strong. The other is a singer that I got from a friend whose sister died and she inherited. She does not sew. It is an older model but has variable speed. I use them a lot. The trick to threading one that is not self threading is to after first time when changing thread is to tie new thread on to old thread. Also tie a piece of dental floss to thread and use as leader when threading from scratch. Makes threading much easier.
