Just bought the Graphire4 for my 2nd computer (I have an intuos3 for the other one) and I love it - both are 6x8, and the G4 was about $200. I used a friend's 4x5 and it was too small, another friend has a big one (guessing it's 12x12 like yours but I thought I remembered it being rectangular not sq) - too big - not to sound too much like Goldielocks but the 6x8 was just right for me. The intuos3 has 1024 levels of pressure while the G4 has 512 - ya know, they work the same for me - can't tell the difference. Hope that helps- -Lew ;-)
