GoPro via eBay offers its refurbished GoPro HD Hero4 Black Edition 4K Action Camcorder for $129.99 with free shipping. That's $10 below our refurb mention from a week ago and the lowest price we've seen. (It's the best deal today by $36 for a refurb elsewhere.) It features 4K video recording at 30fps, up to 12-megapixel photos, a waterproof housing (up to 131 feet), WiFi, and Bluetooth.

Note: A 1-year GoPro warranty applies.
