Tim--I equate dollars spent on gadgets to the amount of fabric I can buy and fabric wins every time. I have the 60mm cutter, mat and some rulers and I have done all my quilting with that for 17 years. I'm not about to change now. I went from the 45mm cutter to the 60mm cutter because I found it gave me better leverage. The 45 is my paper, junk cutter and the other is for fabric only. This way I don't have to change blades for the different functions.
