eXPert PDF Editor Professional Edition
Full user review
"Works well, No Watermarks on Trial Edition"
No watermark on trial edition, unlike many of the other PDF editors. User Interface was easy to navigate after only about 5 minutes of tinkering around beforehand.
User Interface is not particularly intuitive, but once you get the hang of it, you'll do fine. Some characters were not able to be displayed in certain situations (could not use "z" in several spots).
Trial edition is good for smaller edits. If you regularly edit large documents, perhaps spending the cash on a more premier pdf editor is the worth it. However for minor, infrequent edits, this software is just the ticket.
