The questions: is it really going to make a difference to your clientele? Can you spend that money (or 1/4 of it?!!) on other things that will improve your setup and attract new biz? I'm a working pro without it (used to have it years ago) and haven't found it to be a problem to be compatible for projects i do. That being said, if my steady work was still sound or music editing for film, pro tools would still be my platform - it's not and it's not.
