I have been using Tata Sky with TATA Sky Plus HD Setup box. Till date I am very satisfied. The Tata Sky Plus SetUp box is awesome, features like live pause/play, recording, series recording are awesome. Now I never miss any program. I had no issue with customer service. Picture quality for HD channels are awesome, and non-HD channels are watchable. I have a 51 inch TV, and happy with the TATA sky quality.
Only wish they introduce more channels, espeically the HD channels. Airtel and Videocon currently gives more HD channels. But nevertheless, I must say TATA SKY is good.
