Roccat Kave - supposed to be in India this Month. Search Dealers Paradise. Around 7K
btw, are Astro's true 5.1? I think they use that Dolby mixing to get the 5.1 effect like the G35s.
so far the true 5.1's [ 3(+) speakers per ear ] are Zalman RS6F, CyberSnipa Sonar, Turtle Beach HP, Tritton AX, Roccat Kave, Razer Barracuda, Psyko ($300) ,Sharkoon X-Tatic and some others
You can get these from the US via KMD.
