I have the intuos 4 Medium. I find it very accurate for my needs. Second that. I used the big one at work and there's no difference, you'll get more buttons that you'll never use anyway and a bit bigger working area which doesn't matter anyway. But I also like bamboo, it's as precise as intuos, I got Bamboo fun CTH661, it's the same thing imo, just cheaper, has pretty good pressure sensitivity and a nice paper-like texture to it, why don't you like it?
