Hi Have had my HQ16 for 2 years and I love it. I have never had a problem, I do not have the stitch regulator, I do have the stylis, I am the computer.. ha I researched all of them before buying this one. I am lucky my distributor lives in the next town, I have mine stretched as far as I can and have gotten up to 110" wide, so I am very pleased. Quilt trends.com they sell, used, and new, plus demo's or ones used for classes. Chek them out. if that web doesn't work let me know and I will email the site to you.
