Deena, that is the right attitude to have when something like that happens to you! Welcome to the board. You will find a way! Have you seen an occupational therapist to help you master tasks that we all take for granted? That might help you.
I bought a used accuquilt studio last summer. It was an impulse purchase. The LQS near our NJ home was getting rid of it. I happened to be buying fabric, and the sales person asked me if I wanted to buy it. Since I have trouble with both hands, elbows, shoulder, I said yes.
It is the studio model, and the dies are heavy. If I'd thought about buying an accuquilt before I bought what I have, I would have gotten one of the newer ones since the dies are light weight. They do have an electric model, too. The big drawback to it is that the dies are very pricey. Sizzix has a cutter as well. Some of the folks on the board have them, so can advise you about them. I honestly don't know anything more about the sizzix, though.
It has been a God-send with regard to cutting. When your husband masters basic rotary cutting, he can prepare fabric for the accuquilt cutter.
God bless!
