You could get a Bernina that has been traded in from a dealer. I saw a used 200E/730 at my dealers for $3,250 yesterday. I am a quilter and that is one of the machines I own. As a bonus, it is a machine embroidery sewing machine too.
You could also get a used Bernina that is made for quilting only for a heck of a lot less. I wouldn't trade my Bernina for anything.
