Before you drop $$$ or €€€ on a Wacom, I'd check out the Huion 610 for $55 on Amazon.
I used a Wacom Intuos 4 for years then got a Huion 610 and my Wacom has sat in a drawer ever since.
It just works better than the Wacom, for a fraction of the price. The pressure response is smoother and more comfortable, and overall it's more reliable.
Here's an extensive, detailed review by Ray Frenden of the Huion 610, complete with video.
Do your homework, of course, and be aware of the tradeoffs. The Huion 610 may have fewer features than a Wacom tablet, depending on the model.
But in terms of the core functionality of drawing, I think it's a superior product. (And it's A LOT less expensive.)
