Gosh -- I've never thought about the quality of my rotary cutter!! I bought mine in a set --- rotary cutter, mat, and ruler -- at Joanne's a few years ago for $20.00. It's cut MANY MANY yards of fabric. I've sharpened and replaced the blades....but they're so standard, I don't think there's any "good, better, or best". I'd say get the cheaper one and then if you want a new toy, go for the more expensive ones.
