I have this type frame with the tilter legs. It's great and easy to construct if you have a good pvc cutter man. One thing about the half tubes that hold the quilt taunt, the bought frame has grooves inside the tubes so it grabs and holds the fabric when you turn it. I don't know if regular smooth tubes would work as good. You could save enough money to buy the grooved tubes if you built your own frame though. You only need four.
