I have the Go. I like the strip dies - got the 2 1/2 inch die with the machine and just ordered the 1 1/2. In fact ordered 3 from Joann's because they had them all 40% over the last weekend and free shipping since it was over $50.00. When I got the machine I bought the finished 5 in block, the die that comes with the machines (4" block, 2.5" square & 2.5" hst, the 6" & 3" tumblers, then just ordered the hexagon with 2", 3" & 5" hexagon dies, a 4" x 4" diamonds. Haven't done much with it yet, but that is a matter of time.
I don't do the iron applique, so have not thought about buying the other style. So it really depends on the type of quilting you like to do will dictate what you want to buy.
