I have one, I bought it as soon as it was available. It's fantastic for cutting scraps in to ready to sew pieces. The Go is a personal machine and the Studio is for mass cutting. I have learned a lot of tips using the Go from the yahoo group: accucutquilters
The GO dies are not interchangeable with the Studio. There are lots of YouTube videos on using it. I learned how to mark my dies to get different shapes from one die from YouTube.
