If you are looking for a grid based tool, PyxelEdit is pretty nice. It is still in beta, I believe, so the tools may vary in perfection, but it's pretty nice with automatic tiling and you can also create animations in it. It's a single developer developing the tool and from my experience he is really quick and helpful when asking for help in the forums. He also takes suggestions on new tools to implement or feedback on older tools.
The program costs $8 dollars minimum, totally worth it. Check the videos here and decide if this is something you need. I recommend it.
