Thank you. I measured and the 730 has about 7 1/2 inches compared to the 790 has 10 inches and the 880 has 12 inches. I have had issues with the buttonhole applications on the 730. But I would like to join in the embroidery and quilting classes which seem geared towards the higher 770-790 and the 8’s. I do have a few other Bernina machines: Record 830, 1000, 1130, 1230, 335B, 730e, sergers: 2 334DS, 334D, 1300, and a Deco 600. I kind of love Bernina. I also have a very old Pfaff (was my mom’s), Elna ( 1966), 2 Singer Featherweights, 2 Singer 66 Treadles, a White Treadle, 2extra Singer Treadle heads without cabinets, a old Singer (my mother in law’s), a Bernina 1001 and 1010 for my daughters to use and gave my Kenmore to our son. I do love sewing and 5 of the above machines were inherited. We do use all my machines when my girls are sewing and have family that come to use them too. I want to expand and learn more embroidery and especially quilting, thus my desire to have a current machine, but probably trade in one or two machines towards a newer one. I just want to be frugal but look to the future for myself and my girls. Any advice is welcomed. Thank you all again.
