I need to get some more and in the past I've bought from Grizzly and Lowes and a few other places. I have yet to use Mirka or Norton or any of the "better" brands, and was wondering what/where many of you purchase your disks. I have a hook/loop 5" Bosch ROS, 8 hole. I don't need 300 of each grit, just a seasonal hobbyist, but am looking for something possibly better than what I've been using. Thanks.
