I have the Bernina 440QE without the embroidery module, and I love it. It does everything I need for both quilting and non-quilting projects and for garment construction. I plug my machine into a surge protector extension cord, along with my iron, light and fan, and I always unplug it at the wall, making sure (1) everything is off and (2) if there was any kind of electrical surge, my machine would not be affected. My Singer serviceman suggested that over 40 years ago, when I bought my first machine, long before I even knew what Bernina was, and I have been doing it ever since. The nice thing about the Bernina is that you can just unplug the power at the machine instead of at the wall.
