text: where can i buy an adobe photoshop cs (not cs2) upgrade for windows? i need to upgrade my photoshop (version 7), and i have heard that cs2 is much slower and not really that much better than cs?  (is this true?)  i was hoping to find a place that i can find the cs version, and hopefully at a good price since it's not the newest version.  i don't mind ordering from websites as long as they are pretty well-known and dependable.  any help would be super-appreciated.  thanks! you can always try amazon. they sell old software, sometimes even ued and discounted.
