Do you do garment sewing and embroidery also? The B830 is a multi-purpose machine, and the cost and trouble reflect that. If so, a demo model from a dealer will have had all the kinks worked out and could be a good deal. If you are looking for a machine just for quilting, it isn't worth it. You can buy a sit down quilter from Handiquilter or Babylock for $5000-6000, depending on the options and deals going at the time, and use your current machine for piecing. If you want a more traditional machine, Juki has some nice bigger throat machines that aren't just quilters.Pam
