I have a Baby Lock Unity which was a trade up from my Crescendo to add embroidery, and a Bernina 820QE. Hands down I would choose the Baby Lock. It took 6 months of back and forth with my dealer (an hour away) and 5 brands of thread to get the Bernina running. Had to replace sensors and a spring already. I belong to a Bernina 800 series board, and there are people all the time that have had problems with the 800 and 830's. I haven't heard as many problems on the 700's, but once burned twice shy.
