On Jan 6th, Shill posted that he spoke to a local Dish installer and was told that there would be a deal for people who swapped a 942 for a 622.
" I hate to give repeated info and have always asked and never contributed but I spoke with a dish instore rep yesterday. He said if I wait till Feb, I can get a Dish 1000 upgrade for about 60 bucks. He also said they will be changing out the 942's for a mpeg 4 tuner 622? or something like that in February. Also stated it will be available for lease instead of buy."
For the most part, what he wrote here is reasonably accurate, especially for early January. There was a $49 upgrade with a D1000 that came out on 2/1 with the 211 receiver. And the trade-in program of a 942 for a 622 did happen, but not until 4/1.
