I have this machine and use it on a Grace frame. I have the Original Grace Frame. Over the years I have tweaked it a number of times. I have or should say had a stitch regulator. It just died unless I can find a way to fix it. I just had the 1500se in for service not that long ago So new it sings. This last 6 months have been touch and go with it so I am setting up a sample piece so I can fine tune the machine to the frame and tweak it some more if need be. I have been using this machine very hard for the last 9 years or so. I bought the entire set up for about $400. The machine is a work horse. The plan is to be using it today if all goes as I am planning it to go. We'll see for sure. Best of luck with your machine and frame.
