I had the GO for the first 4 or 5 years, and then bought the GO Big and have had it for 3 or 4 years. I have never regretted making these purchases. I don't have any shoulder problems but I still decided I needed the GO Big. I have all the strip dies because I use these on almost every quilt I make - for sashings, bindings and borders. Then I love the pattern dies like the Hunter's Star or Drunkards Path. I was always afraid to try the Hunter's Star pattern because of all of the little pieces but with the pattern die it was so simple, no templates, and all the little pieces went together perfectly. I love my GO Big and if something happened to it I would buy another one immediately. It's priceless to me.
