Premium Direct LLC via eBay offers the refurbished GoPro HD HERO3 Black Edition 1080p Waterproof WiFi Digital Camcorder, model no. CHDHX-301, for $264.99 with free shipping. That's tied with our May refurb mention as the lowest total price we've seen. (It's also $15 under the price of a new unit today.) It features 1080p video recording, 12-megapixel burst capture mode, 6-element aspherical lens, and WiFi. It comes with a waterproof housing (to depths of up to 197 feet), rechargeable battery, charge cable, and mounting hardware.

A 1-year warranty applies, but it is unclear who backs it.
