I called about the $50 Singer 15-91. It is sold. Sure wish people would take their ads off Craigslist when their item sells. Oh well...the search will continue. Plus - I went into a long explanation about quilting, machine stitching vs FMQ vs LAQ to my hubby - so now he is on board with why I would be looking to buy a 3rd machine & why it would be vintage vs new. Yay!
