i like using the acutal refills, but if you need something to do the trick in the mean time. go to a home depot or lowes, and pick up a stick on orbital sander pad. you just cut the size you need and they stick on and are the exact same thing if you find the correct grit. I can't remember what I bought last because I just picked up about half a dozen tools last during the last trip to vegas. Hope it helps or you find something.
