I have a Go that I use all the time. It's easy to store and set up.
I wish I had a big shot pro and the space to keep it. You can cut more layers of fabric and use dies from all the manufacturer s.
But I really don't have the space and do get a lot out of my Go.
I have a book by Ebony Love that has a lot of great info on die cutters. It will answer all your questions and teach you stuff you haven't thought of.
