I have used mostly Adobe Acrobat Pro for pdf annotation, conversion, review and collating documents for pipe stress work documentation activities. Also a short period of time with Bluebeam Revu. Both programs are relatively expensive but are the standard for the industry.

Has anyone used other highly rated products such as NITRO PRO 11, FOXIT PHANTOM PDF BUSINESS 8 or NUANCE POWER PDF ADVANCED which are significantly less expensive that do an adequate job and are compatible with Adobe Acrobat Pro?
