My 1st frame was a Grace Pro and I loved it. Used 2 different machines on it during my time with it. Didn't care for the poles as they would bow so slipped a conduit pole over them to beef them up. Changed out the plastic piece the wheels roll over to a metal "T" strip too. Only problem was I couldn't seem to sell it so gave it away. A couple from another state came and got it so they must have thought it worth the trouble and distance. It was well made and easy to take apart to move to another location.
