I've never used any graphics tablet in the past, but I entirely agree with Cookie's comments on the bluetooth and battery.

Edit: Although, my view on any graphics tablet is that you probably won't use it as much as you think and it probably wont be as entertaining or fun as you thought...

I think in order for it to be worth using it should have some sort of display on it (so you can draw directly where you want to draw) as I'm sure it will make life a hell of a lot easier than having to draw at a random location then move it to the right position only to realise that it doesnt fit, so you have to draw it again etc.
The downside to having a display is the (what I assume would be considerably large) cost.

In my personal opinion I would recommend spending the $250 (or $200 for the non-Bluetooth) in another way, but if graphics design is really your thing then I suppose you should go for it...
