Best Gaming Mouse Logitech G500

Video games. I've been looking for a good gaming mouse since I started playing Computer games. Some of the things I look for:

I want it to be ergonomic
I want it to have alot of programmable buttons
I want it the software not to crash
I want it to be (relatively) cheap...way under $100

I think I've found it with the Logitech G500 Gaming Mouse
