I have a GoBig, the crank one, and I wish I'd gotten the Accuquilt Studio. There are sets of nesting dies that would be just perfect for something I want to do, but they do not fit the Go machines- they are too thick. So, check out the dies and make sure the ones you will use the most are available for your chosen machine. And, since you have back issues, get an electric cutter. Lol, I'll think of you when I'm cranking away on mine!
