Why? It's still there. (As before, for new customers only.) Just go to "Get Dish" in the top menu, select "Order Online", enter your zip, in question #1 select 2 rooms, in question #2 select "I want to pause live TV... and whatch HD". In step 2 select Option 2 "942 DVR" and you will see the lease price of $250 in the quote.
It states on the Dishnetwork Receiver Options that current subscribers can only purchase the 942 from a dealer. I'd like to have one too, but I think I'll wait till the mpeg 4 technology comes on line.
