Hmmmm, if you are on a tight budget, you may consider getting a DigiPro tablet. I got a 8"x6" one for $69  (Canadian dollars) and it works great.  I have talked to several professional graphic artists, and they agree that mostly, all you need is the pressure sensitivity and the feel of holding the pen. They rarely use the angle detection, eraser, or other advanced features.

However, if money isn't an issue, Wacom tablets are of much better quality and will no doubt last longer.
