Best Cell Rendering Options

I am developing a cartoon series for a cartoonist client who has created a legendary cartoon character in 2d which has been published in print for a number of years.

I started modelling the characters in Blender with the thought of cell rendering the scenes. After experimenting with Freestyle, I am still struggling to get acceptable shadeless results with good dark strokes around features.

Has anybody achieved a flat cartoon-style render? How did you do it?

I don’t know if you have seen these already:-

Yeah. I did see those tutorials. Too much shading though.

I did find a very complex setup tutorial. Pity it is not a screencast.
