I love mine and bought my mom one too. It is so much easier to cut strips and pieces. With my OA, RA and shoulder issues, it is about the only way that I can cut straight without help. I made a case for mine (and I saved the $70) and it stores between the cabinet and wall in my closet.
I have thought about the cutters too, but I really hate to invest that much money in dies that I may only us once, if at all. I have complete freedom to cut what I want and how I want to cut it. And it is FAB-U-LOUS for cutting pieces for kaleidoscope quilts. And I love kalei quilts. I'm working on one now.
They do show up on eBay fairly regularly. I have a saved search so that when one comes on line I can see it too. If it is the right price, I might buy another.
