Thanks for your opinion. I wish there were a place that I could go to to try them both out but there isn't. There is a significant price difference, but that is because there is a quilter's cruise control with the GMQ Pro frame. Which of course I don't know if I need or not... And I have read that the carriage upgrade makes a big difference. If the frames are pretty similar, maybe it would be better to go with the less expensive and upgrade the carriage. But then I would have to buy a new Juki instead of a used, less expensive Juki.... ARGH!!!
