i picked my 7336sp up from lowes last week. Its with the sanding machines in the rather large section at the front of the store that has all the power tools in it. mine came out to $116 and change.
Lowes stores here still have them, I saw one on the shelf last weekend when I was there.
If you don't see it on the shelf with the rest of the sanders ask a store person to look it up in their computer. They may have some in back or on order.
I don't think ne1 has used those pads for polishing. You'd be better of getting some "real" polishing pads. They're cheap enough.
