I think my parents got the HD DVR for free at my house some how. My parents switch back and forth from cable to direct tv depending on where the deals are and they seem to get free shit too. I think now in my house we have 6 recievers. Two are HD DVRs and I know my parents didnt pay $200 for each of them out of pocket.
Talk to the company. They are pretty friendly if you can parooze your way to the right people.
