Hi, guys I am going to buy a wacom intuos tablet from ebay to do some serious CG paintings in my powerbook. Here are some questions I want to ask: 1. Is a 4X5" tablet enough to do painting?? Or should I get the 6X8 one? 2. Any differences between the intuos2 Platinum and the original intuos2? 3. Would you recommand me to get the newest intuos3 or just get the intuos2 tablet? 4. Give me some advices and Tips for bidding things in Ebay, pls~!! Thanks!!
