This machine has special bobbins (I had a 430 and have 100 bobbins for that one!) so I phoned my local sewing machine shop, no they did not have it instock, but they could order it, it would only take 4 weeks, so I decided to order it direct from the Bernina shop online. I searched every where all bobbins were there except for the 730. So I phoned them. When I told them the problem they said (and you could hear in their voice, onather one that can't look properly) You must look under bobbins and find the right one, so I told him I had the page open and there were many that said not suitable for the 730 but not one that said use for the 730. With a sigh he said he would look. After a few minutes he humbled down and asked me to phone back in 5 minutes while he mad some enquiries. When phoning back he apologised and said they had forgotten to mention the 730 . He has now ordered them and I am waiting to see when they arrive!
