I'm sold - bought a cutter and blades. The cutters are supposed to allow you to be more accurate and I think will reduce cutting fatigue because it uses different muscles than the usual ones.

Tomorrow (or the next day) I'm going to a quilt shop called A & E Pharmacy - that's not a typo. The owner of Martelli Notions told me to go there. There is no website but I found a blog review. There is one other place I might try - Magnolia Quilt Company - but it's a bit of a drive and there's no website and I haven't been able to find an online review either.
I hit Joann's today but nothing there that I wanted to buy.
