PDF help!

What is the best way to convert a .pdf to a .doc?  Free, that is. 

I work at a small library and we're getting a lot of people bringing resumes in for help, but they're bringing them in pdf format.  I need a way to be able to edit them to assist people in rebuilding them (we're a job help center too).  I'm wondering if we need to buy a converter program or not. 

Thanks, and the public sector thanks you too.

Thanks, I've tried three of the six on that site.  Zamza won't accept the file and the other two leave stamps/watermarks on the .doc until you purchase their $40 version over the trial.  This should give me another three options to try.

If you're looking for software that does what you want for free just search lifehacker.com.  You'll find a post where they highlight some piece of software and the comments consist of users listing every alternative.

I find so much stuff that way.
