Bro it differs place to place..
In my area GTPL Hathway SD STB costs Rs500 and HD STB costs 1500.
Monthly charges rs250 + I'm getting HD channels for Free.
I never faced any no signal issue till now...
Yes place to place. Ur MSO is good, and gives quality service. My MSO is not like that, they have numerous issues and customers are very angry with their services. The issue with MSO/LCO is they charge the customers whatever price they wish.
