If they are in non pattern areas like the sky, I use the path tool. It works very nice and you can't see the photo has been toutched. Just select the path tool, select the area (be gerenous and leave a margin if you have the space for it) and then drag the path to a claen area to replace it for the clean area.
Why would you do this when the clone stamp tool does it automatically? Define diameter, alt-click on clean area, center tool over spot and click...
The healing brush is actually the most useful tool for dust removal, though. If you have neighboring-color problems, you can set it to "replace" in the tool options bar, or you can do a quick selection with the magic wand or magnetic lasso to isolate the area you are working on and the problem goes away.
