I don't have a Go! cutter, and no desire to have one. But I would never stop using my rotary cutters. I have fancy machines and old machines, and use an old 1931 Singer for piecing, it does such wonderful seams and is a very quiet machine. I love all the modern things we have now to make life easier, and no real desire to go back to the old ways. I have arthritis in my hands so handwork is pretty much out of the question. I love my cheap steam iron and really prefer setting seams with the steam. We all have to do what works for us, and for me modern is better.
