Everyone's worth is based differently.........but I am glad I have mine. I don't use mine every day but when I have I was sooooooo happy I had it. I have used for scrap management....luv luv luv for half square triangles, no dog ears. Have used appliqué for wall hangings and runners, made large quilts, baby quilts, and it is absolutely fantastic for cutting wool pieces. I have the hearts, stars and circles and the Xmas appliqués are cute as heck.......
My only comment would be, to really think about the kind of quilter or sewer you are before you purchase dies.
if my vote counted.....I would say go for it!
