@rtwo2008: Online, got the green edition. Red Wraith version costs even less. They respectively cost 69 and 65$ now. Virgin Megastore Hamra must have it for about 100$, 120$ max I think (maybe it's cheaper now).
To mmk92: If you're playing FPS games, then I'd advise you to get the RAT 9 (here's a link with details:
http://www.cyborggaming.com/prod/rat9.htm). What's great for shooting games with this mouse is that it has a side button that puts you into "sniper mode", lowering the speed of your mouse (DPI) for more precision AS LONG AS YOU KEEP YOUR FINGER ON IT. Now, I don't play shooting games, but basically if you're going for a head shot or something, you can temporarily press that button when you zoom into your target to have a precise shot, which is an awesome feature in my opinion.
I was considering getting the RAT 9 at the start, but then changed my mind. However, you must know that it's the ultimate "adaptive" mouse, and can have its weight, shape, speed, modes changed from your desk. It does seem a bit complicated to set up at the beginning though. It does cost some big buck though (I think 120$), so if anything you can get the RAT 7 which is older but cheaper. I haven't really gotten into the details of these mice so I can't really tell you much about them.
Also, it's worth noting that the naga Hex is the best gaming mouse for MOBAs (like Dota and League of Lengends aka LoL).
All in all if you're comparing the two, from what I know:
Razer naga Hex:
Pros:
Has 6 easily accessible MECHANICAL buttons (mechanical buttons are awesome)
Great, easy to use macroing
Allows fingers to relax with thumb rest and 4th finger "lump"
Online Cloud that saves your settings
Beautiful design
Cons:
Glossy feel, might cause sweating for some
Only wired mode
RAT 9:
Pros:
Has "Sniper mode" for an awesome FPS gaming experience
Can be completely remodeled whenever you want to fit your needs
Has 6 side buttons
Can have up to 3 different modes that you can change with one on-mouse button
Comes in wireless mode
Sleek design, comfortable materials
Cons:
Buttons aren't as easy to access as the hex
Mouse customization can be a bit intimidating at first
Only wireless mode option (dunno how you recharge that thing)
