Sorry to respond late, but I agree with the recommendation to look at HandiQuilter. They have both 16” and 20” sit downs at a better price than Bernina. I dearly, dearly love my Bernina sewing machines, but their newer products are too picky. for use in long arms. You want a machine with online support, not just a dealer, and you want to use strong, professional round needles not the domestic flat back needles. Tension on a pro-style long arm isn’t automatic, but once you figure out how to do it you open up an entire world of threads. I have used everything from 80 weight invisible to 50 wt poly to 40 wt embroidery to 30 wt specialty threads to Metallica. You just can’t do that with automatic tension.
