Of the ones I have used, I still prefer Vinces. Longest lasting and best price. Other places to try, Klingspoor, The Sanding Glove, Woodchuckers, and Craft Supplies. I just got some of the green ceramic discs, and like them. They last almost as long as Vinces, but are more pricy. I haven't tried the purple ceramic discs from 3M yet, but Mike Mahoney says they are the best. I also tried the abranet ones (woven, look like screens) that I got through Craft Supplies, and they seem very aggressive, especially at first, and last a fairly long time. I had trouble keeping the 80 grit disc on the pads. When they started to feel dull, I used the eraser stick, which helped some. Funny thing to me is that I tried some dull ones for hand sanding and they still seemed to cut very well. I have some of the Astra Dot ones on order from Woodchucker to try them out and see what they are like. One thing also that I like about Vinces is that the discs are cut over sized (3 3/8, and 2 3/8 inch). You don't have to have the disc perfectly centered on the pad for it to cover the whole pad. I don't know why all the disc makers don't do this. There are some companies that will sell you sheet stock and you can punch or cut out your own discs.
