Welll you guys' must not be looking very hard
Open Office will save natively as PDF and it can open Microsoft Office documents. So that will turn a .doc into a pdf no problem.
Then there is Foxit PDF viewer and their editor. Their viewer is only about 2 megs and requires no install. It's a hell of a lot faster then Adobe viewer, though has a couple limitations - but none that have become a real issue for me.
They also have an editor. The full version is cheaper then adobe but again not quite all the bells and whistles but for most purposes it's more then sufficient. The free version isn't cippled but it puts a Fox-it watermarker in the top right corner of every page.
