Suppose it depends on what you're used to. Personally, I found working on anything smaller than a large very limiting.
i have the intuos pro large, for quick image touch up, a medium or small is fine
Is this a good entry level setup that you could stick with? I know you can get cheap and cheerful ones around 30-40 but is this more suitable longer term?

I remember having a wired version of this size tablet a while back for home use (I used to work in the graphic arts industry). The size is pretty limiting.
