I've currently got a 622 - I want to add another 2 tuners or a 722k to the house. I want to do this myself as I used to install them a few years ago and I know what I'm doing and already have the location wired up for the receiver however they won't ship it to me so I can do it myself. They said go by a location that has them as authorized to process it and do it that way. If I suggested a tech to just bring it to me then they wanted to charge me $99 for a tech visit but as I said I was going to do it myself - does this make a lick of sense to anyone? They mail the sucker and I put it in saves a ton of money on their end. Instead I have to go find a local shop and pick one up so I can put it in myself.
