I have a R.A.T 9 and it's the the f best thing I have ever bought in my life, yer very expensive but absolutely an epic mouse.
You can program all the buttons to do whatever you want so there is almost limitless combos.
Plus they look f sick.
I really, really like the joint venture between Microsoft and Razer which produced the Habu:

Pro: You can scale the DPI (sensitivity) up/down on the fly.
2 buttons under the mousewheel, you don't even notice them but they are there.
2 thumb buttons - you get 2 interchangable panels so you can choose the layout that fits your hand the best.
Loads of customisation.
It looks cool - the blue light CAN be turned off for those who don't like it.
Con: A bit expensive
I also got a R.A.T 9 really good mouse adjustable in every way definately worth a look.
