That's a really great price Linda1. I was unsure if I would like it, so it was a little easier spending $100 to test the water. It comes with the tumbler die, and that is one I would have bought, so I figured it was worth the risk.
I did check the die compatibility list and would say that at least 80 % of the dies are available for the Baby.
But my understanding is that the Baby handles less fabric (they say up to 4) than the regular Go does, and that would be a big factor if you used it often I would think. Obviously, I assume you liked it or you would not have upgraded. What was the main reason you purchased the larger one? Was it the additional dies or the capacity (layers of fabric)?
