Converting PDFs to Office files - do I need to buy Acrobat Standard/Pro?

Hello,

I have an occasional need to convert PDFs to either Word or Excel. Are there options to do this other than buying Acrobat Standard/Pro? Maybe something like a standalone conversion utility or a conversion on demand service. I would prefer not to shell out  a bunch of cash. My wife and son have bled all of that out of me anyways.

Thanks!!!!!

Mike
