While we tend to focus a lot on the TiVo Series3 and TiVo HD, TiVo does still sell the TiVo Series2DT and it is the lowest-cost entry point to the world of TiVo. The affiliate promotion that TiVo has been running comes to an end on January 31, 2008 – this Thursday. Through the promotion you can get an 80-hour S2DT for $49.99 when you sign up for 1-year of monthly service at $12.95/month, or pre-pay $129, $249, or $299 for 1-, 2-, or 3-years, respectively.
EDIT: The offer has been extended to April 2, 2008.
