I have the PE770. I think the PE780 is just a newer model. Mine does not do Disney, I don't mind. You have a 5x7 area, but you can purchase a 5x12 hoop also. Just know that the 5x12 does not mean that you can embroider a 5x12 design. It means that you can move the hoop over to do something else, without rehooping. You can download PES or DST files. I like the PES better, because the DST does not show the picture. The screen is black and white, a little small, but for the money, this is a good buy. I view the designs on the computer. You use a USB stick to load your files on the machine. There are also a lot built in. Good luck with your choice!
