Siloette Thats Smooth

What is the best looking way to take an image and turn it into a monocolor siloette (1 color). I know the best way is to just trace with the pen tool but I have lots of images I have to do and it would take forever. The magig wand leaves lots of jaggys and blurred edges. Anyone have an idea?

Thanks
Adam

I would look at some of the tutorials that Pank has here on "selections", see if any of the methods will help you. After all getting the stuff you want black (or white) selected is the hard part. I might try using channels . . .
