With the new PC model coming out I know a lot of you may be considering purchasing an old 7424 at closeout prices. Please make sure the one you purchase has the hook and loop attachment. Some of the ones selling for low, closeout prices do not have this attachment and if you don't have that you can't use the velcro backed polishing pads that so many of us use. I made this mistake buying a 7424 a while back as a gift for someone and it did not come with the hook and loop attachment. It cost me another 35$ to add that. Just be aware.
