I'm in the minority. I bought the Go and it was way too limiting for me. I sold it and bought a big shot pro and love it. I can use almost any die on the market in it, including the Go dies I had bought when I had the Go. Also I had problems cranking the Go and the Big Shot Pro is so much easier (I think the new Go models have been improved in this department).
On the other hand my sister has a Go and is happy with it. She doesn't mind that it's limiting and for her, portability was more important.
