I have a Accuquilt Studio cutter and have several sizzix quilting (and non-quilting) dies. I just use a shim. Like Dolphyngyrl I also have the drunkard's path dies. The Sizzix versions are on 2 separate dies, making it much easier to cut all the "L" pieces from one color and all the pie shapes from another.
Note that the Go! and GoBaby will NOT accommodate sizzix dies because they are too thick.
