Thanks for the advice.
That one that you just posted is the Wacom Bamboo Fun 5.8"x3.7". It's on Newegg for $100. I was actually considering that one before i found the one I'm currently looking at.
So what do you use yours for? And how well does it work for your use? Also, how good is the pen?
EDIT: After looking a bit further, I have decided that the Genius F610 would not be my best choice, just because it is more geared towards writing, and is not very good quality for drawing.
Thanks to Kultz and Aqua for their great advice and opinions, I have now decided that if I really want what I get to meet my requirements and not fall short AND last, then I need a Wacom.
Now, I am deciding between the Small Bamboo Fun (5.8"x3.7") at $85 (normally $100) and the Medium Bamboo Fun (8.5"x5.3") at $167 (normally $200). My display size is 1920x1200 (i've heard that smaller areas are harder to use with bigger display resolutions). I'll spend the extra money if I really should, but do I need to get the bigger one?
