I have a Artistic dx 26 inch with a Gracie freedom frame. I’ve been quilting for other people for about 5 years now. This year I added a robot and it took me about a week to learn it and get comfortable with it. My machine is built by tin lizzie, which is pretty common. Its not a Gammill but I didn’t have to take out a small loan to purchase is either. The stitch regulator is good and the touch screen is adequate. I will be purchasing the upgrade when it comes out. My advice is to buy from a somewhat local dealer who is willing to teach you. Unless you are good at teaching yourself and are motivated to figure whatever you need out. I’m completely self taught but it takes time. Don’t buy at a quilt show. You never know what kind of support you are going to get and when you have a problem with the machine, and believe me you will, you’ll have to ship it. Plus supporting the local guys is how we keep quilt shops open.
