It really depends on what kind of quilts you want to make. I have the "Go" and used it to make over 300 5 inch blocks - it was great. I like to use the June Taylor shape cutter, but often lose track of which slot to use. (Not an issue with the Accuquilt.) I cut all the strips to bind a quilt in one run through with y 2 1/2 inch strip die. I have a lot of dies, just not made a lot of quilts yet. I want to make the tumbler quilt, so got it, also, hexagons and circles for yo-yos. Someday I do hope to make the double wedding ring quilt, so went ahead and bought the dies when they were on sale.
For me - it was well worth the cost.
