I read a post about sandpaper that offered the suggestion (affirmed by at least one member) that Norton 3X was the best.
Anyone care to share a best price supplier?
I was able to purchase a package of 9" Adhesive-backed 80-grit disks for my sander from HFT for less than Peachtree charged me for shipping three finer grit no-name disks at nearly three dollars each.
Just got this sander (from HFT $150) and now must find a supplies supplier.
Thanks for any links, suggestions.
