Think we may be waiting til summer, we have two dishes on the roof (one I believe was pretty much for the distant networks) and are having a new roof put on this summer...so thinking we should wait and tie it all together and have the one dish removed the same time the roof is done AND do the hoppers. I'm leaning towards two hoppers, more for the reason of if one fails we have the other, have had the 722k's fail a few times since we've had them. And because I'm just not adept enough to do all the other mirroring would probably have to get 2 joey's as much as I don't want to. Are the super joey's going to be totally wireless? I sooooo detest the though of all those stinking wires. it's so nice now with the 722k's - just one cable each up from the basement and of course the connection to the tv. I hate wires. Hate them.
If you do go with a 2H/ 2J scenario you can always figure out a way to do the mirroring later as you become more comfortable with the system. Then when you do you can just send a Joey back to Dish and save $7 a month, or if you can send the 2nd Joey back too you're up to $14 month savings.
