Diane - I've been happy using ImagePrint's toning and split toning capabilities. It's not that easy to use their preview image to see how things are going to go color-wise, but with experimentation you can come up with some very subtle and interesting toning effects. I'm mostly using a 7800 and K3 inks on Innova Photo Smooth Cotton paper.
