I started out with the original AccuQuiltGo cutter back in 2009 and it has given me great service. However, arthritis in both hands, has been acting up so I sold it and bought the Go! Big electric cutter. The nice thing is that I can use my current dies. Strip dies of different widths, although more expensive than the smaller dies, are great for cutting squares, diamonds, etc. Even bias binding strips. There are a lot of helpful tutorials online. A local quilt store not far from my home offers a periodic class on using the cutter. It does not matter if it is manual or electric.
