One challenge you may have is that many early versions of the program needed to activate components (the ability to edit and output MPEG, for instance) that activated by contacting a web site. I don't know if that's the case with key components in version 9 but, if it is, most likely those activators are long gone.
Crazy cheap is one thing, but not if if meets you cripple your workflow. Do yourself a favor and find a copy of version 11, 12 or later. It'd probably cost you less than you'll spend on Tylenol trying to work with version 9.
