Even with the full version of Acrobat Pro (which IIRC is closer to around $250) editing PDF files is tricky and clumsy at best. I've done it quite a bit and one of the problems is you have no way of knowing what application the PDF came from. Word on a PC makes very different PDFs than Quark on a Mac does, and even with the full version of Acrobat, if you don't have the actual font used in the document in the area that you want to edit, you may not be able to change it. That said, BY FAR the easiest and most successfull program for editing an existing PDF file is Adobe Illustrator (CS or CS2) which uses PDF as it's native format, but if you aren't familiar with using it, it's not like typing in Word. In many situations I have found it easier in the long run to recreate the document rather than fighting with the PDF to make changes. You can cut and paste text blocks from Adobe Reader into Work (or whatever) and fix up the formatting and get real close. There are also quite a few applications that will convert PDFs to other files like Word or Excel. I've played with them and some work real well, but in the end I have Illustrator so I've had no need to convert something to Word, so if someone else needed that would be there issue, so there's never been a need for me to buy it.
