You can get your hands on a refurbished TiVo HD DVR for $199 with free shipping, directly from TiVo. The box can hold up to 180 hours of standard-definition footage or up to 20 hours of HD content.
The refurb boxes carry a 90-day warranty and service fees start at $12.95 monthly, $129 annually, or $399 for a lifetime subscription. You also get access to Amazon's video service and streaming Netflix movies, too. If you're not quite on the HD bandwagon yet, you can get a dual-tuner standard definition TiVo box for $79.99 instead. But everything's better in HD. Except Larry King. And just about anyone over the age of 60, really.
