It looks like the best, would be the integrated
DPPlus Triple LNB used with dish 1000.2.
It would give you 110,119 and 129 for HD, with the option to hook an additional satellite location with another dish, using a (single or dual)
dishpro LNB.
It would be able to feed up to 3 single or dual tuner (using a $5 DPP Separator) receivers without any external switches.
