I have had a VIP722 for years in my house and a 510 receiver in my barn/mancave that also doubles as my RV receiver. A tree (50 ft oak) has grown to the point that the top is interfering with my reception of the western arc. It's time to move to a eastern arc dish (to get HD locals). This will involve planting a new pole in the ground. I'm thinking this might also be the time to switch to a Hopper and a Wally. I need the Wally because my barn/mancave is 150 ft behind my house and has it's own dish is also my RV receiver. I would also want to have the dvr option on the Wally. What would this entail cost wise etc. I only feed 1 extra tv with the 722 so I guess we would need 1 Joey as well.
