I'm about to purchase a larger quantity (at least for me) of sanding disks. I've been using the wavy edge, 2" and 3" and of course I'm looking for the best deal. So, three questions: 1. do you think the wavy edge makes enough difference to pay a couple pennies more per disk, 2. Do you have a good resource for the type of disk you really like, and 3. What is the type you really like.
I've checked Craft Supplies, Klingspor, Packard, and found some (but not the wavy ones) at Turningwood.com. Any other places to check out?
