I have a very old Homesteader without stitch regulation. I put a used PC quilter on her (aka Bertha) a few years ago. Basically edge to edge, but I can use her to quilt without the robot. She is still performing beautifully. 19" throat Loves to be loaded with cotton thread and is a beautiful machine. I have rails to extend her to 10 ft, but haven't done that. I do mostly small quilts for charity or as lap quilts for friends. Perhaps by now you have found a system which you are pleased with! Happy quilting.
