If you are just starting out or on a budget, there is nothing wrong with going with one of the affordable Wacom line. I got a Bamboo for something around $50 but that was years ago but both the stylus and tablet are still working after years of abuse. Do pay attention to the size in comparison to your screen. My small works well with my laptop but it feel weird when I plug it in to my wide screen desk top.
If you want to upgrade to an Intuos then, do some
diligent research because the series has bundles whose main difference is software that comes with it (not counting the most expensive of the line, Intuos Pro). If you are set with using PS, as I would too, I would just stick with Intuos Draw unless you want the touch capability for some reason.
