Lately I've been taking the linework, xeroxing it (play with the contrast), sharpen up the lines after and then scan it in. I have a sort of cheapo scanner too that is going to be replaced as soon as I can afford a decent one.
That Wacom line sketch looks cool but I also like the original. You could probably get the same look with a black marker. I have yet to try one out and justify the outrageous price. It would have to be a very drastic improvement for me to invest.
It really is more personal opinion than anything...personally, I think money could be better spent on good traditional drawing supplies or maybe Photoshop. Just my $.02
