When I upgraded my PC last year, I had to pension off my old pressure sensitive tablet as I could not get drivers for XP. Last week, I bought a new Genius Wizard Pen 5x4, and used it for a restoration over the weekend. I can't believe how I've missed the pressure sensitivity, especially when using the airbrush...
BTW, here in South Africa the Genius is 20% of the price of the bottom end Wacom
