Are there any mice similar to the g9x ? is it possible to completely disable the acceleration on the g9x
Cooler Master Xornet and the red version with higher dpi come to mind, and the price is usually right. Some people won't like the ring finger rest, while other people will realize what they've been missing.
G400 has an area to put a ring finger too, just different.
G400 is a nice universal mouse and known for good quality, though kind of feels like you're gripping the top half of a football.
