I have a Wacom pen and tablet, but I'm thinking of trying to find something even more sensitive if I could. Money isn't really a problem because my office will pay for it, but I'm not really sure what I should be looking for. I would love if I could get something that i could see being drawn as I draw it. But not quite a tablet computer, I need to be able to hook it up to my desktop in order to show clients as it's being drawn. Any suggestions?
