I owned an Opal 690Q for a couple years and loved it. It had a ton of functionality and sewed just about anything I threw at it without issue. It was a fantastic machine. In the end it was the space to the right of the needle that made me look at other machines. I made an unfortunate side trip with a Topaz 50 that was rough, but now am happy with a Brilliance 80, which like the Opal sews everything.
