I have an accucuilt go and love it but the dies are expensive. I have quite a collection of standard quilting shapes: strip sets, tumblers, hexagons, triangles, squares, etc. I still plan on getting traditional quilting dies for my go.
if I want let's say a duck for Easter, it is too expensive to buy the die and you only get 1 - 3 small designs on the die. But for $.99 with the silhouette I can get pick from thousands of ducks or if i have a duck I like it has a feature that will trace and cut it - it's called print and cut, for free.
