I've never used the Flynn frame but I have the Fabric Mover thing for my Viking (in the box, under the bed). As Klue said, you try it at the store and watch the demo disc and it's all being done on a small quilt sandwich. The lady in the demo disc is smiling and you think it looks pretty simple. NOT!! Anything larger than 24x24 is next to impossible to quilt-the area is simply too small. I guess I should add that this is just my experience and someone else may be able to give some better insight or had better luck with the Fabric Mover thing. As for me, it's just something I stub my toe on every night when I get into bed. (And expensive at that; I don't know the cost of a Flynn frame so can't compare)
