I am very fond of my Go. But is it worth it to you? It all depends on what type of quilting you do. It certainly makes cutting strips quick. I can usually cut enough strips for all the binding of one quilt in one run through of the die. And I cut 300 - 5 x 5 inch squares of Christmas fabric for a 75 x 75 inch quilt using 73 fabrics in about 2 hours.
I have a lot of dies that I have tested but haven't used yet.
