I bought the Flynn and it is awful. It was cheap but not easy to use.
You have to go to Home Depot and get pvc pieces to roll the frame around on, and they have to be just the right diamiter to fit the heigth of your machine. You have to keep it level yourself as you quilt and the pvc has a tendency to roll off the table as you quilt. You can only quilt a small section between the throat of your machine and the roller your quilt is on.
Also it only comes with short pipes to roll your fabric on so you can only do a small quilt. You can buy longer pipes but then it would be even worse to handle.
