I’m looking for a free (not web-based) free pdf editor. I don’t need to create fancy stuff, just simply edit existing text in files and import pages. Simple stuff.

Any recommendations? Most good ones out there cost over $100.

PDF-XChange free version if you insert another pdf into it will put a watermark on the pages. It's $43.50. Might be worth it, but checking if there are other suggestions that are better.
