Thanks all for the clarification. Dish wouldn't sell me a 211z, so I bought it and a Playmaker from a private party. I know the Wally is a better unit, but I was afraid of all the reports it needed all three sats in sight to work. I wish Dish would sell a multi-tuner/dual-output receiver that is powered directly from 12volts - the RV market keeps expanding and such a unit would be a perfect fit..
