I have the 830 with the quilt frame. While it has some issues..I think some of mine were/are learning curve issues. But I am so in love with this machine. It does so much that I don't even know yet! The only down side I have came across is you can't take the whole bobbin housing out if you get a bad nest. It must be taken to the sewing Dr. Other than that it sews like a dream and I LOVE it on the frame. I can finish a quilt in a few hours. I never have been able to get the BSR to work right with mine though. I know its me and not the machine. I end up using the embroidery foot to do my quilting. I hope this helps you. The only diff between the 820/830 is the embroidery function...right?
