Ahh, good to know. I was actually considering a Wacom Intuos tablet, which is said to be quite similar to the previous Bamboo series. The good thing about it is that it comes with a free art program which actually allows me to use it, lol. I don't think Paint.NET supports pressure sensitivity... :(
Personally, I use a Wacom Bamboo MTE-450A. It's an older model (one of the oldest, methinks), but, even in its age, the pen sensitivity is good and it's quite durable. I don't know how easy it'd be to get one though, as I'm not sure Wacom still makes them (I bought mine from a friend). Either way, I'd recommend Wacom products, in general. Don't settle for anything less! Wacom is the best!
