If you are an artist and want to draw digitally, an Intuos 3 tablet is worth the investment.
The Graphire is good as well, but doesn't have the amount of pressure levels or tilt sensitivity as the Intuos does. I had a Graphire 3 and later upgraded to the Intuos 3, and it made a lot of difference in my drawing.
I highly recommend the Intuos 3 tablet.
