that's my someday dream- to have a long arm. with just 4 years of quilting under my belt, I'm getting closer to the goal of feeling experienced enough to handle it. I'd love to find a used one close to me where I could learn before buying.
Perhaps- look at the "big picture" too- are you committed to quilting and will you use it enough to make it worth the investment? Then reserch the heck out of it.
