I have a Singer 15-91 (my favorite), a new Sapphire 735 - these two I use. I have another old black Singer in a cabinet and a 1957 green Singer that holding up my cutting table right now. I also have 2 sergers and 2 more sewing machines that belonged to my mom, just no room right now to have them all out. I really love the zigzag on the 1957.
