I am staying in one location while working during the week, and living at home on weekends... I want to have Dish at both locations, and was wanting to just add a DVR receiver to my account and install it at my other location. I currently have the 622 at home, but just need the standard dvr receiver at the other location. What would be the best and cheapest way to get a dish and receiver so I can install at the work housing location?
