Hi - I have a Tin Lizzie 18. It has a stitch regulator but doesn't always work. My husband has to keep adjusting it and roughing up the rails for better contact. I've had it for approximately 6 years so perhaps they've improved it. I also wish I had a bigger throat than the 18" as I have now started a long arm quilting business. At the time I was purchasing it, I was looking at best quality for least amount of money. Good hunting. I know there are some good machines out there.
