I have the Studio cutter, which was given to me along with more than a dozen dies. I've listed in on Craigslist and offered it to people through quilt guilds for $800 and less with no interest shown at all. I've even seen another on Craigslist, same thing. One woman who was very knowledgeable about the thing offered me $150 and I said no.
The Studio is discontinued, I believe. You can use GO! dies if you have an adapter, which is just another piece of plastic to raise the height of the die.
I'd hold off on that one and maybe ask the woman to call you if she comes to her senses, er, changes her mind about the price.
