Wow! Interesting reading about the BSR. I have an 820 and despite having taken it to the dealer and had the new spring put in, it is still skipping stitches. On a 42 by 48 inch quilt yesterday, it skipped 4 times. I also have an issue with the auto threader not threading at times. I have to rethread the whole thing numerous times to get it to work. I discovered yesterday that turning it off and back on and then rethreading worked. Go figure. I have mine set up on a Pinnacle quilt frame. I tried pushing quilts through by hand and I just didn't have the hand strength to do it. I do find this Bernina is quite picky about everything as compared to my old Janome 10,000 which just sews through anything with any needle and any thread at just about any tension and never skips a stitch! Too bad the throat is so small and it has no stitch regulator. Otherwise I'd never buy a Bernina!
