I not much of an artist at this moment but I am friends who are and they use Wacom computer drawing products. http://www.wacom.com

i currently use a Cintiq 12wx. it is a tablet with a screen that you draw on: http://www.amazon.com/Wacom-Cintiq-.....pr_product_top

it is pricey and i feel it is not worth the money.. the screen has flaws: it's not bright enough, and the screen is quite blurry. but being Wacom, the pressure sensitivity is great. I however do not recommend this product :/.


my first drawing tablet was the Wacom Bamboo tablet, which you can find at the link Leonardlion_o gave!
it is not a screen tablet, but it is a great tablet for a cheaper price!! I have not tried the newer versions of bamboo, I had an older model from about 5 years ago... I am sure the quality and buttons in it now are awesome!

Like many have said before, a wacom tablet is your best shot, they are somewhat cheep and well worth it, because I've had one and they do last forever, and really good to start with.

I had to get an iPad for school, but I found a free sketchbook app on it. It's not perfect, but its what I've been using to draw lately.
