I have a Wacom Intuos 2 9x12, costs a lot, but the freedom and space I love. I can put a full peice of paper down and trace my scetches into the computer. I had a 4x5 and I always found it to small, my hands are large, and trying to hold it or set it right was always a bother. The 9x12 I lay infront on my lap and infront of the computer and just draw anyway, gotta work with the room you have and how your style is. "If you can afford one I highly recommend it"-Farris Bueller
