I am too embarrassed to tell how many-----they are all over my house. I sold most of my stash so that I would have some place to show them. All work but 3 that I am still trying to get going or find the parts for. I have used them all but I favor the Singers 201, 301, and Featherweight.....I even "loaned" my Bernina to my sister (her White gave up the ghost)because I would rather sew on a vintage machine.....
