It depends on how much cutting you are going to do. the Baby may be too small for you Check to see what dies work. The Go is not much larger and most likely will give you more flexibility. One die you may want to check out is the 2.5" strip cutter. I believe the GO will accommodate that one and the Baby might not. There is a yahoo group devoted to the accuquilt system. Lots of good information there. And...purchasing one depends on how you will use it. You can really become addicted to getting dies.
