I have one of the original Sizzix and would have to buy a bigger one for the wider dies. I've used the accuquilt and the Sizzix, and sorry, Accuquilt has the battle won hands down. The Accuquilt has the ability to cut large dies easily. The handle is much easier to use as well. Accuquilt also has so many dies that are made for Quilters. The Accuquilt seems to me the exact same machine used in most public schools (usually elementary) to make all their boards in class as well as projects for the kids. Many quilt stores allow you to rent their machine and dies. The dies themselves are different and similar, Sizzix uses plastic for me on the bottom and sides, Accuquilt uses wood on the bottom.
