DO NOT BUT A WACOM!!!They are simply overpriced....Get the trust one instead
http://www.trust.com/products/group.aspx?coll=TABLETS. I've got the TB-6300 one. They have MASSIVE working spaces compared to the wacom ones and are much cheaper. Just check the great reviews.
Have you used a Wacom tablet before? I've just gone from an A4 trust tablet (granted, it was not branded as 'trust', it was a generic tablet which trust took and branded (like they do with a lot of gear) I used the trust drivers.
iirc the OEM was either Waltop (

The active area of the tablet is personal preference, but I see absolutly no need for mamoth tablets. A6 is too small, A5 is just right, and A4 is pushing it. the large and extra large tablets are made with specific uses in mind. for art purposes though, A5 is fine. When I was using my A4 tablet my arm would be killing by the end of the day.
Wacoms are generally far more accurate, their stylus don't require batteries either. It's all in the small details too, like the two parts that make contact with one-another - the stylus nib and the surface of the tablet. Intuos tablets come with an array for different nibs from hard, felt, rubber and sprung nibs to give different feels, and different tails to lines. the quality of these 2 parts can be the difference between being able to translate your intended actions, into what you see on the screen.
The trust ones are decent, don't get me wrong. but only regular Wacom users will know the advantages of having a wacom tablet. There is a reason that they are pretty much the industrys standard tablet.
I'd never say that Wacom gear was over priced, but rather, you truly do get what you pay for. It's the same with most things, especially artistic materials and equipment.
