You guys probably know all about this stuff but we lead a sheltered life down under in Australia! Anyway we have just discovered Abranet from Amazon. You can get a $23 starter kit that includes a velcro adaptor pad. This stuff is sort of like those 3M abrasive bristle brushes. The pads are wooven and completely breathable all over. We got onto these looking for a cheaper alternative to Festool pads which sell out here for around $2 and never ever seem to go on special. There are no generics here at all. The pads are simply brilliant and very very fast with only light pressure and totally dust free using the Festool vac. You really notice how good they are sanding cypruss pine. Those lines you get on the really dark knots after drum sanding just melt away. In our book anything that makes sanding easier is worth a bash!! And yeh I know the pics upside down!
