Yesterday I tried putting some normal 40wt cotton thread in the bobbin but I continued to get skipped stitches and a birds nest (still the top thread). I called my dealer and the only suggestion was to rethread the top. I've done this already (a few times). If that didn't work I was told they'd have to evaluate the problem. I'm assuming this means they'll take a look at the machine. As far as the skipping stitches they said they'd need to talk with a Bernina educator. Honestly I don't think that will do any good because I believe there's a design flaw in the Bernina Stitch Regulator as I had this same problem with my 440 (even after the updated spring) and have read tons of other people's complaints about the same thing.
I wish it was as simple as saying, "I'm unhappy with the product, it doesn't work correctly, please give me my money back."
