I agree that their site is difficult to navigate and it's annoying to me.
You could buy the die that cuts charm squares. (5x5) That's a good one.
Also triangles, rectangles.
I bought the Go and like it a lot. I haven't gone wild buying dies. I have a strip die for making binding, and mostly just blocks that I will use a lot, like the above mentioned.
It's fun cutting them out!!
