GoPro via eBay offers its factory-refurbished GoPro HD Hero4 Silver Edition 1080p Action Camcorder, model no. CHDHY-401, for $179 with free shipping. That's tied with our expired mention from three days ago as the lowest total price we've seen. (It's also $100 under the best price we could find for a new one.) It features up to 1080p video recording, up to 12-megapixel photos at 30 fps, waterproof housing (up to 131 feet), WiFi, and Bluetooth. A 1-year GoPro warranty applies.
