You can get 4 satellite locations on one receiver. You have to use an SW64 switch for 3 of them and combine it with an SW21 for the 4th location and then select the "superdish" option when doing the check switch. It worked for me at least. Though I think some really old receivers won't do this.
I subscribed to the Denver and LA distants. Dish added both CBS HD E&W for me at no extra charge. So I now get Nashville, Denver, LA, & NY CBS feeds. Very Nice.
