It took me about 6 months before I picked mine up (I like piecing so much more than quilting). I read the book, watched the DVD, the boyfriend helped me set it up... and I LOVE it. I can do a queen size quilt in 7 hours. And it's much easier on my back/neck/etc then when I would pin baste and try to fight with my quilt as I was FMQ, and pulling, and pushing and the bf holding up parts so I wouldn't have as much drag, and that was just painful. This one, not so much. After an hour or 2, I do take a break and stretch, but really, after an hour or 2 of anything, you should take a break :). I also have so many quilt tops that need to be quilts. I spent 3 years just making quilt tops since I hated the old way of quilting. Now I'm actually finishing them, so that alone for me is worth it, since otherwise they'd never get done.
Best $100 (or however much) I've spent.
