I bought a wacom 12x12 for my comp at home and I love it.LOL I will say it is a little weird at first but man it is alot better for detailing your work. As far as what size or how much money to spend, when I got mine i tried to get a tablet that best represented the size monitor i have. My 12x12 almost matches my works space perfectly. I use a 22" screen. I would go 9x12 for 17" screen. HAHAH and then there is your budget to think about.
