I just purchased the Altos Quilt Cut 2, but I haven't had a chance to try it out, yet. It's not cheap. But there are no additional dies to purchase. Based on the included CD videos and the printed manual, it'll cut just about any geometric shape. The cutter also holds one end of the ruler making it easier to hold the ruler steady. Holding the ruler steady is one of the more difficult parts for me in getting straight and accurate cuts.
