No, it is not for zero dollars. I will have to replace reliable owned receivers with with leased POS receivers at the cost of $10 month each. That certainly is not free. I will drop to one receiver because one of the Sony's was used for the VCR which died die years ago.
Leasing is a stupid business model to me. The original AT&T dropped it decades ago. But, if I am to get anything more than over the air tv, it seems that I must lease some sort of set top box from someone with the monthly cost going on forever. I would gladly buy a new receiver when the legacy guide goes away, but I won't be allowed that option.
Sure, the new receivers have more bells and whistles. I expect that when I get a new receiver, it will be like many things I own. I will be paying for features that will never be used. Or they will used only once to see if they are useful and those features really aren't useful to me.
There will be no change to the cost if you take a like-4-like replacement, which most customers are doing.
DTV is replacing an old, SD receiver. That receiver is a $6 a month mirroring \ lease fee that is currently on your bill unless it's the only receiver in your house. The replacement receiver is the same $6 per month and will take the place of the old one. No change in cost.
If you decide to upgrade instead of taking a like-4-like replacement, then you may incur other charges for those additional services like DVR, HD, etc, if you don't already have them on your account.
But there is no incremental cost to you if you are replacing it with the same kind of receiver. Just make sure when you connect the new receiver (it is shipped to you), that you call to disconnect the old one so you aren't being billed for the second receiver.
That's it, you'll be good to go.
EDIT: I see you are going to get a HD receiver for your new TV. That would change things, just make sure when you order your HD receiver or HD-DVR, that you have them deactivate the old MPG legacy receiver.
