Originally, PDF export in OpenOffice.org was limited to three levels of quality, whose exact differences were obscure to most users. But that was many releases ago. The latest versions of OpenOffice.org provide, for no cost, most of the features available in Acrobat Standard for $299 -- to say nothing of a few features that even Acrobat Pro Extended does not include even at $699. The problem for many people is knowing what options they might want, especially since the wording of the dialog window is sloppy in a couple of places.
