I have a Wacom Bamboo Fun. I LOVE it. I believe there are 4 Bamboo's now.
I just purchased the Intuos 5. I have read great reviews on it, but have not tried it yet. I do have high expectations, simply because of my first tablet the Bamboo fun.
I'd say if you are going to continue with Art, then worth defiantly worth the investment! Hope this helps.
