I have an Accuquilt Studio cutter and I like it but I don't love it. What has been a better tool for me is my QuiltCut Fabric Cutting system. Yes, it requires the handwork of rotary cutting, and if that's something you want to cut down on due to hand pain, then the Studio is more help. However, I find I cut far more on the QuiltCut than I do on the Studio. I have to be in a mood and have fabric lined up to make the most of cutting on the Studio. The vast majority of the time I'm using the other.
For what it's worth, I did find a local plastics company from which I bought replacement plastic cutting sheets for a fraction of the price, so there are options to bring the expense down with the Accuquilt system.
