Advice on stylus and sketchpads
My daughter has shown a keen interest in drawing, and has recently requested that she can continue her small anime style productions in a digital environment.
She's asked about an electronic sketchpad and stylus or equivalent, specifically speaking about ipads and tablets type devices and the like.

I have absolutely no clue in this area, has we any graphic artists who use similar, what hardware and software combination do you use?
Does it integrate into a PC, or is it stand alone?
How expensive was your setup?

Thanks very much for the info guys.
Sorry I was slow to come back to this.
I feel she wants something that she can physically 'draw' upon a screen, so I'll look that direction probably
