I would look at used machines, since you are just beginning, you might not stay with quilting. Theres no use putting a lot of money into a new machine that can cost $6,000-$12,000. Also older used machines have less bells and
whistles which make them more user friendly. Look at Bernina 1090, or QE150, (180E for embroidery machine)
Sew on several brands and find one that works for you, be sure to buy a name brand machine,
plan to spend $800-$1500 on a good used machine.
