When you initially subscribe to DTV they want you to use new equipment. Once you've activated your account you can add all the old DTivos and receivers you want. You should be able to get some good deals as a new subscriber but that usually means getting the hardware with no up front fees or out of pocket costs.
Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!
