If you are in the USA, consider taking a course at a local college. As a
student you qualify for a substantial discount. The student version is
the same as the commercial - only the EULA is different - you are not
permitted to transfer the license in any way.
WOW!!! That sounds like a great tip - as long as the tuition is worth
it. I'm somewhat comfortable with PS already.
I find a student in my family or friends to buy it for me. All that is
needed is someone with a student id. I usually buy at a college bookstore.
It is upgradable when the next version comes out.
