I restore images professionally, so Photoshop is really the only choice for me. It's now even more expensive, you can no longer buy it, you have to rent it by the month or year. IT SUCKS! I am very unhappy with Adobe, to say the least. I'll be using CS5 until the operating systems change so much it will no longer work. At this point, there is no substitute that I can find. I use many layers in my work, along with other special tools available only in PS.
Here's a color slide, Ektachrome, from one of the Casey Jones Excursions with NP S-4 #1372, as scanned and restored. What you don't see in this small example are all the dust and scratches removed from the image.
