My neighbor is now having a new Genie installed (2-22-2012, 12 noon). Since I am also thinking about switching from "E" to "D" I started asking the installer some questions. I asked which DVR he was installing and he said the HR34. When I told him I was interested in switching to the Genie set up he suggested that I wait a week when they will begin installing the HR44 exclusively. When I asked why he said that the HR34 is being phased out and will no longer be serviced. Not sure what he meant by that but it sure sounds like the HR44 is the future for "D". By no longer being serviced I assume he meant that HR34 replacements will not be stocked and if one needs to be replaced it will be replaced with a HR44.
