I looked at the site and was surprised to see the $998 price with standard support (the lowest level possible.) I have used Adobe Acrobat since version 1 in the early 1990s and do not think that I have spent that much including the original purchase and the upgrades since then.
DeskPdf Professional from Docudesk for $29.95 provides more features than the standard Adobe Acrobat package and almost as many as the Acrobat Pro version. I use it on additional machines I have here and seldom miss a feature included in the Adobe Acrobat Pro package.
