Free app to convert .pdf to either word or another format

Hi all

Does anyone know of an app I can download that will allow me to convert a .pdf document to either a word or .odt document.

I use both neo-office & word

I would prefer a free app, but even a cheapish one would do (I think Adobe is about £800 for this)

Thanks in advance

Phil

Thanks I tried that, but as you said the formatting was all over the place!!
