I have a mid-arm..a Pfaff on a Grace Frame. The frame is fine....I have no problems with it. BUT, if I'd had a choice (a friend sold me this cheap) and the money, I'd be buying a long-arm. With the mid-arm you're restricted to quilting patterns about 5" in size. With the long-arm you can quilt much bigger designs......and you wanna guess which size I keep picking out?????????????
