We have a Bernina 820 from 2009 with a Bernina Quilt Frame. The frame is 10 Feet but can be used in 5 foot sections. Very sturdy and heavy duty steel built. The 820 includes a stitch regulator has been professionally serviced by a Bernina Dealer and is in excellent working condition. I will ship everything for free. Price - $3795.
The frame is very easy to set up and will include all of the parts and pieces including leader cloths. You can actually purchase automation software for this set up called Quilt Motion. The Bernina 820's have 12" of space to the right of the needle and with this set up, you can do king sized quilts. The best part about this system is you can take the sewing machine off the carriage when you want to sew.
If you have any interest, please let me know. The pictures of the frame are only set up in 5 foot sections.
Thank You!
