Any recommendations of good pdf writer software

Hello,

I am looking for a software that allows me to convert various documents ( such as MS Word, Excel, etc ) to PDF files, easily and fast. I have searched on Google but I'm not satisfied with the results so far, the free ones add advertising or watermark texts, and the paid ones are not very easy to use.

 

SonicPDF is good - it's what I use anyway.

 

Thank you for your suggestions! The best seem to be Cute PDF and PDF Writer Pro ( http://www.amicutilities.com/pdf-writer/ ) , I will also compare a few other, and then make a decision of which to buy!
