SBG, three years ago I bought a 550 Bernina, but still sewed on the 1530 inspire Bernina. The older machine had to be sent in to Chicago to be fixed, so I am using the newer Bernina now. Didn't know how to fill the bobbin, had to learn. It fills it automatically, and I want control over it, but that's not how its built. It sews a straight seam. That's all I really want.
