Guys - go and have a look at Super Cheap Auto.

They sell a gizmo called a "Bohler 3d sander"

It does not come with polishing pads - but they sell a "Mega Pack" which includes buffing and lambswool pads.

Sander is $20 - mega pack is $30... I think it's a steal...

It's variable speed, and nicer than hanging onto the drill...
