I have sewn on the 550qe and the 765 for an entire day on each. For me i have not been impressed by them for what they cost i think there are better machines out there with more features and more user friendly. I have used quite a few brands of high ends out there and the only bernina i would shell out dollars for is the q20 imho. I am definitely a brother gal. I would try as many machines as you can before making your decision because i have heard the newer ones dont compare to the older models
