Very difficult to find good gaming keyboard prices in india...anyway I saw a logitech G1 gaming desktop for 1.5k in bangalore...theres also the G11 which is out of production but u may be able to get it for less than 2.5k..then theres the microsoft reclusa for arround 2.4k...But the absolute best gaming keyboard u can get is the logitech G-15 but it is a hefty 4k and theres also the razer lycosa which is also expensive at 3.5k..
Microsoft reclusa for 3.5k
Razer Lycosa for 4.6K
Razer Tarantula 6K
if you can wait.......
1. Microsoft is going to come up with its own gaming keyboard completely built by themselves.
2. Saitek products are coming slowly in indian markets.... the distributor is Abhinav futuristics (as u know its CEO is the olympic gold medalist). they have got the saitek gamers keyboard and Saitek eclipse keyboard.
G15 is a great keyboard, Microsoft has also released this

name is SideWinder X6 keyboard and X5 mouse
Your best bet seems the Logitech G1 right now . Extend your budget to 3.5-4k and get the Razer Lycosa which kicks some serious a$$. The ultimate keyboard is the Razer Tarantula which is, well way out of your budget .
I dunno if its available in India but the ZBoard Merc2 is also a kool keyboard.
As for the multimedia take look at the Microsoft Ergonomic Keyboard 4000 . Its priced around 2k.
My bad, its 2.7k . Anyways, go for it blindly. As per the gaming keyboard, the Logitech Gaming G1 seems to be your best bet.
