Was just wondering if anybody could give me some info on doing a receiver swap that i'm thinking of doing come Feb. due to the charge for dual tuner receivers.So what i was thinking of doing was swapping my VIP 722 for a VIP 612 because i don't really use the second tuner and cannot not see paying for it,so what i was wondering is i just used the dishin it up last year and can't remember if they offer that every year or every 2 years but probably wouldn't matter because i would have to wait till june or july of this year if it's every year.So wanted to get some feedback on swapping receivers as far as price and other people's experience doing this.
