if you are buying it to machine quilt on, I would suggest one of these instead.
http://machine-quilt-frames.blogspot.com/ He hasn't keep the blog current this summer, but he does have a frame currently listed on ebay. Just do a search for track & carriage quilt frame and it will pop up. It is much sturdier, and glides easily in all directions. It isn't quite so mobile as the Flynn but IMHO it's the better bang for the same buck so to speak. I do not have either one, but have quilting buddies who have both, and the ones with Kenneth Lund's track & carriage system LOVE it. After watching his video tutorials I'm sold
I'm going to be getting one of these soon I hope, but since we just got a major deal on a floor frame for hand quilting it is going to have to wait.
