I also recommend the G5. Though, if you have the money, maybe look at the G7. The cord on the G5 has a nylon sleeve on it, which is extremely stiff. So, if the cord bends and you take your hand off the mouse, it shoots across the table - which is very annoying.
Other than that minor nuisance, the G5 is a super sweet mouse.
