Buy Wacom bro. Have had the first Bamboo for, well since it was launched, probably 8 years ago? Still using it, works well and lasts. Yes it is smaller than you want, but personally I prefer smaller ones since you don't have to move so much from one side of the screen to the other. It also depends on the resolution of your screen though. At FullHD it is a bit small maybe, tiny movements will have an effect.
