well unfortunately the one mouse I would suggest for you costs more over there than it does in America.
it's the Logitech G602 and over there it's $5,589 INR on discount.
if you can afford that, it's much better. While the DPI may only go up to 2500, at 2500 it's extremely fast and sensitive, and you can customize the DPI levels per switch level using software and can customize all the buttons on it, even the scroll wheel and left and right clicks.
