News flash - On a recent visit to the new & used CD shop in my town the proprietor was using a grinder/polisher specially designed to make beat-up CD's look new. From a distance, it resembles one of those water centrifuges they have at some laundromats. I had a look inside the unit. Around the central platter it was lined with a build-up of pasty-looking, white, CD dust. I'd never seen one before so I asked about it. The guy was unabashedly proud of it. He keeps it right out in plain view. What a shocker!
