So I'm a grameenphone modem user and I'm sick and tired of it (no offense). Now, I made a post like this before, but then I realized that there are other good ISP's out there.

Now, if I'm correct, these are the good ISP's currently available:
Go broadband (it's new)
Teletalk (super 3g version)

Which one should I get? I need something at/above 1mbps and ping needs to be less than ~70ms.

No, I can't get fiber broadband.
