I got a copy of nitro Professional (older version). I picked it up (unopened) at my usual hangout, the thrift store. $3.00

Does what I want - edit files, extract pages, convert to Word (not too well).

I think you can download slightly older versions for free to see if you like it. Google is your friend.

ETA: What I mean by 'older versions' is versions just before the present one. I think the current version is 8, so 6 and 7 seem to be downloadable.
