Razor Habu

Im thinking of buying a gaming mouse for FPS games and i cannot decide between these mice:

Microsoft Habu
Razor Deathadder
Razor Lachesis
Logitech G5

Need help on which one is better and please list the reasons why.
General tips and suggestions are welcome

= Thank you]

I have the G5. I got it for about 6 months now and I love it. The tray and adjustable weights on the fly DPI changes are amazing. I tested the two razors on your list and I prefer the G5. The Habu I have not tested. I love my G5, and highly recommend it.

Logitech G5

All my Logitech mouse FPS were, and before I bought a PS3 that I have a G5 to play OpenArena (based on the Quake engine). The G5 is strongly recommended by the players - I've already done all the research.

G5. I have been using one for a little over a year now. I used others too, and I found the G5 to be the most comfortable.

Logitech is the best in my opinion
