inkahauts - I hear you, but you're still assuming you're getting a Genie for free from Directv and that it is an HR44. If I want to guarantee a HR44, I was told to buy it from SolidSignal or WeaKnees and I would have paid $300 for it. Your calculations all assume a free Genie from Directv and assume you're getting an HR44 even though a lot of folks have been reporting getting HR34s.
If you want an HR44, you can do what many folks have done. keep rescheduling the appointment until tech shows up with one
