Brother makes an XL3500 but it's not an embroidery machine. Juki makes a 3500 but it's not an embroidery machine either. I don't know of any others :( I owned the PE 150 embroidery machine several years ago when I first got started with embroidery. I didn't want to spend a lot for a machine if I didn't use it much. It was a good little machine. I upgraded and my SIL now has that machine.
BTW, Bev....Babylock and Brother are made by the same company :)
