I have the Sizzix Big Shot Pro and use my Accuquilt dies in it all the time. I did order the adapter from Accuquilt, but you can made do as PaperPrincess said by using magazines or something to raise the die to the same thickness of the Sizzix dies. I also use the Accucut Studio dies in my BSP and don't have to use a shim or adapter with them.
