Polaroid Dust and Scratch removal - a free utility from Polaroid that's supposed to make it easy to remove dust and scratches. In addition to normal use, there's also a plugin mode for Photoshop included. Worth taking a look at (I haven't tried it yet). By the way, the installer is pretty dumb - it searches all mounted volumes for plugin folders, but of course can't find "additional modules". Rarely such a dumb idea, especially with my 120 GB Firewire disc ...
