Perhaps some kind soul could offer some advice here. My wife is wanting to subscribe to Sky Angel. She only wants it on one TV in the house. Until this evening, I'd never heard of their service and know nothing about their picture quality or customer service. However: we are existing cable customers. She understands that we will 1) Have to purchase a receiver 2) Pay for installation 3) Purchase a Sky Angel subscription. Is all this "do-able?" What type or receiver should we buy? How much would one expect to pay for installation under this scenario? Lastly, how much is a full subscription package to Sky Angel? Is the service reliable? Thanks. DW
