I saw this cutting system at the recent Quilt Market and Festival. I was impressed with all three of the machines.
The Studio is the heavier industrial machine. Has an extensive number of dies and is able to have custom shapes made for it.
The Go model is more for home use. The size is more limiting and has standard dies avaiable. Not possible to have custom dies made for this one. The Go Baby is the new smaller size and is useful for very limited cutting because of the overall size of the cutting bed.
The Studio retails for $595 and they were giving a $100 discount at the show. The Go is about $316. Dies cost in the range of $30-$80 and up for the larger dies.
The recommendation is that if you are doing lots of cutting then the Studio is best. For individual use the Go and Go Baby is very suitable. I don't know if they are available at any discounts such as JoAnns etc.
Interest was brisk around their booth and they sold almost all they had in the booth
