I currently have a 722 and a 722K that was running 1 HDTV and 1 regular tv on each receiver. I now purchased a 3rd HDTV leaving the 3rd one w/out high definition. If I switch to 1 hopper and 3 joey's I'll lose a tuner, which probably isn't all that big of a deal I suppose. Would the price go up significantly with this change or is there a better setup? Thanks. Edit to add: I also have phone service through our cable company, not sure if that changes anything w/ Hopper needs since it uses one of the cable wires I believe.
