PSP, for pretty much the same reasons as Fishnose. Brush Tools and Layer modes are my #1 picks as I also work with layers of renders. I don't paint on anything either, just improve on what's there. Although I've recently gotten Ravnheart's PSP Hair Brushes so I can add additional hair effects. Eye Candy 4000 and Flaming Pear, definitely must haves.
