I've been contemplating on getting a tablet for myself, and it seems the Wacom Bamboo Pen tablet is the best cheap one to get right now. I've had a few things break on me, especially my Saitek Eclipse II keyboard, so I'm trying to be extra careful on what I buy. T.T
I found Bamboo and Intuos tablets to be shitty. There's a disconnect between your hand and what's being drawn.
The point is that the Bamboo Fun and Intuous tablets are more efficient than using a mouse when drawing or painting. It takes little time for your brain to adjust and correct for that "disconnected" feeling you mentioned.
I have a huge Intuous at work but a smaller Bamboo for my much desk at home due to my need for a smaller footprint on that smaller desk. Aside from the Intuous' more advanced features, the size difference is what I most notice, and that is not really a problem worth mentioning.
