Steve,
All of the class 15 machines are vertical bobbins and so are many of the Stylists. So are the 115, 301, 221, 206, 306, and 319. The 31-15 and -20 are also vertical bobbin machines and these have a
huge working space to the right of the needle. As the class 31 is an industrial it weighs a ton. I think the class 31 would be a great FM machine especially on a frame.
