Like the title says, I've got ideas that need me to be able to edit PDFs (not merely annotate or sign them, but actually change text or move it around within the PDF itself, not as a "layer" on top of the text), and for that, need an editor. I've used Adobe before for Windows but it's a VERY old copy and I don't have a windows machine anymore anyway. With that in mind, are there any apps that you all have used for PDF editing on the Mac? Price is an issue, naturally, since I don't want to buy Adobe's offering; but I figure anything less than that will do. Folks?
