Also, keep in mind that the Sizzix Machine only has a 12" opening, so that eliminates it being able to use AccuQuilt Studio dies that are larger than 12" - which is most of the strip cutters & classic shapes like Double Wedding Ring and Drunkard's Path.
And I've run GO! dies through my Studio - it can be done but AccuQuilt won't tell you how. :)
However, I'd venture to say that if you have a Studio, this isn't a big deal, because 99% of the GO! dies were already released on the Studio. You can use Ellison & Sizzix dies, plus all the dies that AccuCut Craft & AccuCut Education offer, and you can have CUSTOM dies made for anything you can think up. That's THOUSANDS of dies - I wouldn't consider 15 dies that the GO! has and the Studio doesn't as a deficiency against the Studio. :)
