I have the older version of PDF Expert. For the most part it fill my needs. I was pretty disappointed that the latest version isn't free for me. Goodreader also came out with version 4 of their software. I'm thinking I should buy the latest version of the PDF software so that it'll continue to get supported with updates. Goodreader 4 is tempting as it's on sale for $2.99. Need help to figure out which software to go with.
