Sister in-law has a 722 with three other boxes (non-DVR) in the house. Their DP switch is maxed out. She needs to add another box to her account for her son who is renting a remodeled barn outside. What are their best options? Another dish with it's own box? Add another DP switch and run cable to another box in the barn? Or would she be better ($wise$) to get the Hopper for the main and enough Joey boxes for all other TVs? I was asked about it and did not know for sure the best course of action for them. Thanks in advance.
