I would have the cost for the first Hopper as well, of $99. So it would be cheaper to go with DIRECTV and get the additional discount on the second year.
HMC $99 + 3 HD Receivers free, and one HD receiver at $99 = $198
It would be great if I didn't have to have two hoppers for 4 joeys. I need my hopper in my bonus room, and a joey for my living room, and bedrooms 1-3. So maybe the DIRECTV Home Media Center would be a more cost effective option?
