We have DirecTV now, but just a single room setup. We do have an extra cable running into the basement from the dish though. So, I would like to get another receiver and use the extra cable on it, since it is only about $5 more per month (it is, right?). I'm just looking for a basic receiver, nothing special. So, I've looked only at Radioshack's site, and I see they have a basic receiver for $125 and a complete one room system for $25! What gives? Does the single room one require a new customer and activation within a given period of time? It just doesn't seem like I should have to pay $125 to get a receiver when I can get the entire system, just use the receiver and have the extra dish in case something happens to our current one, all for $25. Could somebody explain this to me? Thanks.
