No any dth is perfect on all aspect. D2h already give info about removal of channels from base pack, we know it never happen but in case if broadcaster demand more then they need to charge more. Otherwise d2h is perfect on the economy price, no one can match with them.
Airtel dth hardware as well service is good in quality but lower end packs are not too good but higher packs are impressive, especially all sport channels including hd is not costly.
Ts is good in term of quality as well in hardware but hd access fee is very worst in ts. It makes costly to ts subscription.
Dish tv is not suggestable at any angle
