So are Lcd tablets where you can see the screen on tha tablet? Thats pretty boss - but might hurt my eyes, and get a bit confusing?
More precisely, the tablet IS a screen -- it is not a mirror of the monitor image, but an independent display.
My monitor is 20-21 inches big and i have a huge resolution, what would be the best size - id be mainly looking to sketching and "painting" so not really an sweeping curves.
Resolution is fairly moot as most modern tablets provide way more resolution than the screen - even 2048x1536 (twice my screen resolution) is only 192 dpi, and my modest Graphire3 provides >2000 lpi.
and maybe this one:

although £100 difference between the products, is that £100 worth the difference in quality. Don't mean to sound arrogant - but money isnt really an issue - id rather get a better quality product even if it costs more, but if the £100 difference doesnt make much odds then i'd rather go for the cheaper one.
Intuos has far better shielding from radio interference (has not been an issue for me) and tilt sensitivity (might be good for painting).
Every artist - even oil artists - substracts from his strokes with strokes of different color over them, so pressure sensitivity is overrated. You could work with a brick no-pressure black brush in photoshop and with a brick white brush and with adding and substracting you'd eventually get what you need.
movement tracking is what you need in a good tablet.
Movement tracking is definitely the most important.
Pressure sensitivity for anything but size can indeed be very overrated. However for size, I've found it key to maintaining a consistent style (the important element being that to maintain style I need to quickly get down something that not only looks about right but has about the right stylisms.)
Pressure sensitivity for size is really nice for shading and detailing much much quicker than usual. On the pixel art side, it can speed up custom dithering a lot.
It doesn't need to be very precise, though. (64 steps of sensitivity would be plenty for me -- my tablet has 512!)
with twice the pressure sensitivity, but you'd have to make some pretty extreme (extremely long and drawn out with varying levels of pressure) strokes to notice a big difference I'd think :p
Actually, additional pressure resolution is primarily useful for software-based stroke smoothing (more data implies better ability to guess at the intended result). Having a smoother pressure curve can be useful for any function that depends on pressure (eg size, color, subbrush, opacity, color jitter, brush distribution jitter..)
