I'm not sure how much weight to give their reviews... They also said this about the 921:
"The Dish Player-DVR 921 is the first widely available satellite receiver with a built-in digital video recorder (DVR) that can record standard and HDTV programming. Despite its steep $999 price tag, the DVR 921 is an excellent all-in-one solution for Dish Network viewers who want to time-shift their HD viewing with ease."
First widely avaiable? I think not... May never be "widely available".
Excellent all-in-one solution? I think not... Only for 'geek' types that like to play...
