IF you don't want to get screwed with outrageous additional receiver fees , you need to make sure you pick no more than a 211k as your second and third receiver.
The price for duo tuner dvrs( 522,625,622,722,722k) as additional receivers, after the first is now $17.00 fricking dollars per additional receiver.
If you have the solo dvr ( 512,510,612) as additional receivers after the first it is $10.00 each.
If you have the Duo or Hd duo receivers(322,222,222k) you will pay $14.00 per additional receiver after the first.
The price of a solo ,hd solo receiver ( 301,311,381,501,508, 211,211k,411) is only $7.00 per additional receiver after the first receiver on your account. The cool perk with the 211k is that you can add your own external hard drive to it and pay the ONE time only fee of $40.00 to turn your 211k into a dvr. Applies to all 211ks on your account. You can record two channels at a time - 1 sat and 1 ota- if you connect an ota antenna to you receiver. IF you don't want a dvr , you can still get a 211k and just use it as a regular receiver.
IF you steer clear of the more expensive receivers as your additional receiver, you would pay no more than $14.00 a month and you would get hd on each tv in your house assuming you have the 722k or 922 on your main hd tv.
