The Juki TL2010Q is not just for FM. It's a regular high speed heavy duty straight stitch machine with a rectangular harp space so many quilters have used them on a mid arm set up. They stitch beautifully but need to be oiled regularly as they are a mechanical machine. I have mine on a old Superquilter frame and it stitches just fine. It's the frame that is limiting my quilt size(can only handle up to about 70") not the machine.
