I have a Bernina 830 and love it. Wasn't always that way. Hook had to be changed and tension settings adjusted and adjusted again but once everything was fixed, I love it! You can tell the quality. I love so many features - knee lift, needle up down, walking foot, etc. Oddly enough, unlike what Mickey2 said, I like FMQ better without the stitch regulator. My recommendations are frequent cleaning of bobbin case and regularly oiling it. I do it with every bobbin fill. I also would recommend learning how to adjust the tension. There are many good YouTube videos on it. Bernina has many YouTube videos on multiple subjects. I would recommend you buy from a local dealer because they offer free classes and many of them and it is easier for servicing.
