Neat little package
.
I have a tiny 'Genius' tablet, it's like 4"x3", but it's 9-pin so it works fine with my old mouse. I bought a hand rollerball to go with it - so I have the hand roller in my left hand for menus and options, and the tablet on the table and I draw with my right hand - pretty neat little setup for the entire £30 that it cost.
Be sure to stick a piece of paper over it - keeps it clean and gives a more traditional surface to draw on, like some nice quality sketch paper will make it feel more like your drawing and will slow your strokes down, which is a good thing.
[EDIT] Nice to see your back btw!
