I cut the cord recently and have two DRD435RHs and a D12.
I paid lke $70 for the D12 from DirecTV, but when I called to cancel they said I did not actually
pay for it. I refused to send it back and they billed me for an addition 60$ for the D12.
So I paid like $130 for the D12 out of principle.
Let me know if you cant find a D12, I may be willing to let go of it.
I have no use for it any more.
