If you go with Razer, do the Lachesis. I have one, very nice mouse. Doesn't track far up at all when you lift up the mouse.
If you do Logitech, go with the G9. I have this mouse too, and it's a very nice mouse. Much more comfortable than the Lachesis (IMO) and comes with two grips. I didn't find the weight necessary since it's already heavier than the Lachesis. The only thing I don't like is how high it tracks when you lift it up.
The one on the left is a Deathadder. I returned it the next day, didn't really like it.
