Best Buy offers the TiVo Bolt 500GB Unified Entertainment System for $129.99 with free shipping. That's the lowest price we could find by $20, although we saw it for $19 less last December. This 4K-compatible streaming media player/DVR features 802.11ac wireless and records up to four shows at once. (A TiVo subscription is required, and not included.)

Also available is the TiVo Bolt 1TB Unified DVR for $199.99 with free shipping. That's the lowest price we could find by $30.
