I have the Go and would buy it again. I have the rag die and it works great. Many will post the dies cost too much. That's part of it, the system never gets boring. You have to replace the cutting mats as they get worn out but they are inexpensive. Remember to put a thin piece of paper over the die blade before the fabric when you cut a rag block. It keeps the strings out of the die. The only die I had problems with it not being accurate was the 6 1/2" square but found out I was not cutting on grain so the fabric was stretching when the die cut it. The other shapes and sizes I haven't had a problem with accuracy. I cut out every piece of a DWR queen size quilt in less then 30 minutes Sat. If I had the Studio model it would have taken about 10 minutes!
