Thank you for replying, your comments help me with was I already afraid of: I think there's too much risk involved in buying software on ebay, especially when the software is Photoshop. I'd like to buy it because I have used when I was in school (for a comic course) and have tried the new demo: I can not get the same output with other graphic programs I have tried (on my mac). Maybe for now I'ss just stay with my Painter Classic and gimp :( . Or eventually go for Photoshop elements, at least until I can save more many for the full Photoshop CS.
