I have one, and it's okay with a lot of practice, but you are limited in the "top to bottom" of your design by the depth of your machine, I found that as I roll the quilt, the first pattern across the quilt is usually bigger than the area you have at the end of the quilt, because the quilt is now rolled up in the arm area of the machine and it limits the quilting space. Small quilts on it are better than bigger ones when you have to manage the pipes you're rolling your quilt onto. Hate to baste though so I'll keep using it from time to time.
