Which HD DTH is best suited for me?

I am getting a new HD DTH connection(normal HD Box NOT HD Recorder), probably tomorrow.
But I still can't decide between Airtel, Videocon and Tata Sky.
My requirements are low monthly cost, good PQ and good service. Working well in the rain is also critical...
Since I want to keep monthly costs down, I plan to take the basic compulsory package and supplement it with the HD package.
That way I figured I can get the the best PQ (full set of HD Channels) but a relatively low cost (since I am not subscribing to any other SD packs)...

BTW these channels are very important to me :

1.) ESPN HD
2.) Ten HD
3.) Star Cricket HD
4.) National Geographic HD
5.) Discovery HD
6.) History TV18 HD
7.) Star World HD

Thanks in advance for the help guys...
