I own a nice one, but can't for the life of me thread it. So it sits. I use to take it to the LQS where I bought it and have the woman rethread the ones that came undone, but she insisted I learn to do it myself. I can't no matter how much I try. I won't go back in and ask for help again. She made it known she didn't want to keep doing it. She did it about 4 times and I'm too embarrassed to ask her for her help again. So it's of no use to me. I tried selling it on the Quilting Board even, because I'm not using it, but I guess I was either asking too much or no one wanted a used one.
