It all depends on the price range.
Wacom is mother of all artist tablets and most of the top cartographers on this site use them.
Max uses Wacoms Intuos tablet, and I know a lot of other artists do as well.
I myself currently use that bamboo and it is nice, but pretty small and not as free moving as I would like it to feel.
My next major purchase is going to be the Wacom Cintiq Hybrid. It is kinda pricey but looks well worth the price point.
However for under $100, the Bamboo is a good way to go.
