Amazon.com usually has some leads to older and legal versions... I got my Illustrator 9 that way. Adobe does farm out their old warehouse items to other vendors. You just have to check the seller's track record, which Amazon does have for many of their vendors. And look for the notation of 'Unopened', 'sealed box' etc. I was able to legally register the copy I got with no problem.
