Thank you all for your interesting replies.
I work in animation and post production on a PC machine so FCP wasn’t an option (although I dream of it many times…).
The majority of my work is done in AE so I have production pro CS4 and can’t live without Photoshop, Illustrator, Flash for some animation and web tasks; So I assumed the financially logic thing to do is to use PPro. But apparently money has no place when one seeks perfection.
