100 should be possible with some patience.
The Intuos pro S I have is pretty cool by the way. 169€ New with wireless kit, which very nice.
But the tablets surface is a bit soft. No big deal.
When I started using wacom I thought big tablets are the way to go. But now, I feel quite comfortable with the Intuos S when I am not in my Studio.
Wacom stopped suporting Intuos 2 in 2014. I wonder when they'll stop supporting Intuos 3 driver wise?
My Cintiq is Intuos 3 technique

Sure, one can stick on old driver for a few year... Depending on OS progress. Just to consider.
