I have the Go and love it. Watch for sales on the dies. They do have sales on the Accuquilt website. I use it mainly for shapes as I can still rotary cut strips. I may not use it for months but when I want circles, stars, or the other day I needed 24 6" squares and 12 5" squares to make a fold and stitch wreath, it is outstanding to have.
I think of my Go like my big ole roasting pan that I use for Thanksgiving turkey. I may only use it a few times a year, but when I need it, thank goodness I have it.
