I can strongly second the recommendation for Acorn. I'm not a graphics professional, but it is very often useful in my job to have access to an editor on par with Photoshop—which, aside from some of the more advanced stuff, Acorn definitely is. It's extremely polished and well-put-together—and can also both read and write Photoshop PSD files.
