Hypermicrosystems via eBay offers the refurbished Cobra 1080p Dash Cam for $44.99 $49.99 with free shipping. That's $5 under last month's mention and $81 under the the lowest price we could find for a new unit today. It features a 160° field of vision, 1080p recording, auto-save on impact, and Bluetooth.

Note: A 90-day warranty applies, although it's unclear who backs it.
