^ yep, i got them...and they aren't cheap. unfort, i got them before i realized KB makes some lol. i have an extension too because even though i don't have the little Flex rotary, i can use these on my Makita and it will serve the same purpose.
the problem with using these little 1 and 2 inch pads on a DA is the range of motion for a DA is WAY bigger than the pad, so, while you'll be able to work on a much smaller area with a 1" pad and plate on a DA than you would with what you probably currently have (3" pad, 2 7/8" plate), you still won't be able to work in nearly as small an area than if you had a rotary and that 1" pad/plate.
