TiVo has started implementing plans to subsidize their DVR hardware with a monthly fee, so Premiere is now yours for free if you agree to a 2-year contract at $20 per month. Of course, you have the other option if you don’t want to be tied down that long. You can pay $99, if you are willing to make a year-long commitment.
The TiVo Premiere XL will cost you $299 with a one-year commitment if THX-certified recorded shows are what you want. Just pick your poison.
