I Have a Brothers Disney that only uses the 4x4. Bought the PED Basic in April. In Nov. I got a great deal on a Bernia Deco 330 that has the 5x7. Came with the older Magic Box. Wish I had bought the magic box instead of the Basic to begin with. You never know when you JUST MIGHT get a different machine and the magic box Reads and writes to 4 different size cards. Each machine uses a different size card. The PED only writes to 1. Love having both Machine.
