I have two Berninas and a 1950 Singer Featherweight. My older 180 is what I use for piecing and garment making and repairs. I bought the 440 for the Stitch Regulator and Emboridery. I'm not having much luck with either one .
I'm to far away from dealer or anyone I can get training from. My Singer has been with me 55 years and goes most time that I take a machine and I can hem demin Jean on it with no problem, more than I can say for the others. Yes repairs and maintenance on the Bernina is costly.
