you can download a FULL 30 day trial from Adobe's website. I use it as my main source of photowork, I use photoshop for creating some images, but that's mainly when I want to create a certain effect (example - Out of Frame)





For my HDR work that I showed some of, I use photomatix pro 4.0, and all my editing is done on a macbook pro with the screen profiled specifically for Adobe / print for what it's worth.
