Good for you! I bought mine at the Road to CA a few years ago. Kind of felt guilty at first, but got over that quickly once I cut out my first quilt in a record time and all the pieces were the same size. The June Taylor Shape Cutter is nice but I have accidentally used the wrong slot more than once. That does not happen with my GO.
Enjoy it! Watch for the sales and before you know it you will have more dies than you thought possible. (I keep a list of them on my phone so I don't accidentally buy the same one twice.)
