So far I've gotten the best results drawing the whole thing by hand and having it scanned at staples for five bucks. Any time I'm going to use my cheapo all-in-one scanner, it's just to scan in a rough drawing that will be re-drawn digitally anyway. The only way to know if it will work for you is to experiment.

I have also found the table to be less accurate ( anything wacom is good quality tablet. I bought an off brand once and ended up giving it away as a present ), resulting in shaky lines. You can eventually draw nice smooth lines with it, but that takes a lot of practice. It's strange looking at the screen and drawing on a smaller pad at first. You can tape a piece of paper over the surface of the tablet to simulate drawing on paper.

If you get a tablet, make sure to play around with the sensitivity options and different nibs until it feels just right. It's a very customizable tool.
