I have used the connection from these guys (G-Broadband) before.
I remembered, when you gave Mani's number.
They are a pain in the ass to deal with. My internet would be down for days and no one would pick my call.
Do, let me know how is G-Broadband serving you so far?
I was using Tikona, and I feel you should give that a try.
They have a 1499/- plan with 4mbps speed and NO FUP.
I was happy with it, the only reason why I got it disconnected was, due to a new building being constructed in my neighborhood, the signal strength got reduced and I faced frequest internet outages.
I am currently using BSNL, the speeds are consistent. But it's VERY laggy.
I have given up online gaming completely.

Tikona, used to give quite good pings on Asian and European servers.
