It's worth it to me because he cuts are accurate and fit together with no problem when piecing (I piece by hand). I just finished piecing one and all 12" squares fit together perfectly. No trying to adjust so the square match. I may not all the dies I have each time I make a quilt but many of them are typical sizes for squares and HSTs. My DH insisted on buying it (I didn't want it) but don't think I could have done as well on this quilt without it.
