I have had a Bernina 155 for about 10 years. My sweet husband bought me a 750 QE for an early Christmas present. I was afraid that I would not be able to part from my old friend 155 but the new 750 has been wonderful! I am still learning to use all of the features but I am so happy with my new machine! I love the dual feed and the BSR. My 155 will go to my sewing room in our beach house. I could never part with her!
