From time to time we come into possession of TiVo DVRs that already have lifetime subscriptions. So you can buy one, and never pay a monthly fee on the unit.
Further, TiVo charges $399.99 to $499.99 for the lifetime service alone. So these units are a great deal, especially for a new TiVo user who would be at the $499.99 price point.
We’ve just refreshed our inventory of lifetime units. See our page listing TiVo DVRs with prepaid Lifetime Subscriptions.
