I would buy the Fiskars Fuse instead....way cheaper. And then buy the Accuquilt dies to use with it.
The Fuse has a better crank ratio, making it easier to turn, and fewer turns needed. Plus, with adapters, you can use almost any die in the market with it (Studio dies don't work).
The Fuse is in between the Go! and the Studio, in my mind. Very nice and easy to use. Bigger than the Go!, a little less than the Studio.
I'm in love with the die cutting concept. Saves so much time! As far as fabric waste, I don't see it being a factor if you take a moment to plan how to lay the fabric out on the die ahead of time. The most I ever waste is 1/4" around the edges if it's a shape. On the strips I don't waste anything more than what I would doing it by hand with a rotary cutter and a June Tailor template.
