version, student version or an older version? I'm looking into getting Photoshop. I would use it for school and hobbies. I'm not in design school or anything so I don't NEED the latest, greatest for that.

So... what do you think is best for my money? Student, full or older version?

Older version is cheaper and I can buy an upgrade, but by then it's not much cheaper than the full, new version. But I wonder if I really need the newest version? Maybe an older version has everything I need?

Student version is cheap but can't be upgraded. Do you think this is vital for the future? (Obviously it depends on the person... but if you were spending gobs of money for software, would you get one you couldn't update?)

Full version. Self-explanatory and expensive.

Which would you recommend? Which would you buy if you were me?
