I have the 936 Huskylock and I love it. Not at all hard to thread, I just watch the video every time. I don't use the coverstitch feature but it's a great machine with differential feed. Once you get it threaded you can just tie the threads of the new color and not have to totally rethread each time. That works on all of them. I had a Brother but it was awful. Broken threads and needles all the time.
