When I lived in the city my guild had an Accuquilt Go, and my favourite use was cutting things that would be annoying to cut by hand. I would never have made an apple core quilt cutting by hand, but using the die I was able to cut a good-sized throw in under an hour.
I'm planning on buying a Go, and the top dies on my list are Winding Ways and apple core. It really depends what sort of quilts you like to make.
