@Sparker0i Bro I have seen your another post on Tata Sky HD, looks like you are trying to compare Dish and Tata sky. I have taken new connections for both of these recently so I will brief my experience.
a)You can buy Dish TV for cheap price on Amazon/ebay but Tata Sky is bit costly than Dish.
b) On Dish if you pay 230 for Full on HD pack (on top of any base pack) you will get all HD channels available on Dish irrespective of your base pack. On Tata sky by paying HD access fee you will get only those HD channels for corresponding SD channels available on your base pack.
c) Dish tv packs are definitely cheaper but Tata sky has better picture and audio quality.
d) I used Dish Joy Pack + Telugu pack + south regional full on HD pack i.e. 100+51+230=381 per month.
On Tata sky I am now using Sports Dhamaka pack + Sports Dhamaka HDAF i.e. 399+125=524 per month.
Both offer almost same channels(apart from their exclusive channels) but quality is better on Tata Sky.
So now decision is yours, choose as per your needs.
Let us know in case you have any questions.
