It's become just another favorite piece of my quilting equipment. I'd willingly change sewing machines or brands of rotary cutters, but I wouldn't voluntarily give up my die cutters.
When I decided to buy my cutter I thought it would help me work my way through my scraps and make the baby quilts more quickly. It hasn't worked out quite that way. I'm not making more quilts, I'm making more complicated quilts. More triangles, more curves....more fun new challenges. That pieced border on Extra Scrappy Pinwheels would never have happened without my 2 1/2" triangle die!
There's a ton of information out there about die cutters. Quilters seem to either love 'em or hate 'em, and the ones who love them have very definite ideas about which cutter and dies you should buy.
