I also own a Razer Mamba (the old 5600 DPI one, not the new 6400 DPI one lol). If you like to switch from wired to wireless mouse depending on the situation, then this could be a good choice. However, be advised the the Razer Mamba is... a really expensive mouse.
Hope it helps.
Note : Now there are the RAT 7 Albinos Edition (looks like a white RAT 7 it seems, but with 6400 DPI sensor), the RAT 7 Contagion (wich seems to be exactly identical to the RAT 7 Albinos Edition) and the MMO 7 wich looks like a RAT 7 with 13 programmable buttons (is also have the twin eye 6400 DPI sensor as well). But i didn't try any of those.
