you can use any sizzix or accuquilt die as long as it's not a pro die, if it's an Accuquilt die you need the adapter, it's 15 on amazon. I have the Big Shot Plus and I use it all the time and it's wonderful! no pain to turn and super accurate! I have a 6" finished square die and a 2.5" strip die, and I snagged the cat from Accuquilt on sale and got the adapter and I'm cutting cats out of small print cat fabric with my Sizzix. I have like 10 dies on my wishlist for Christmas gifts lol. I'm thinking about getting my mom a Big Shot Plus for her birthday, rotary cutting is painful for her as well.
