@ranjthkumar Hi Bro, I think cheapest pack with HD sports channels is available on Dish Tv.
Go for Dish Tv Joy pack (Rs.99) + Telugu Regional Add on (Rs.51) + Game on HD pack (Rs.165) which makes it Rs.315 per month. You get Sony Six HD, Sony Ten1 HD, Star Sports 1 HD, Star Sports 1 Hindi HD and Star Sports 2 HD sports channels on this.
You can pay Rs.65 more and subscribe for Full on HD pack at Rs.230 per month which gives you all HD channels available on Dish tv making total cost Rs.381 per month.
If you want best quality I think Tata Sky would be best but will cost you more, but if you can compromise a bit on quality Dish HD with above pack should be good.
