GoPro via eBay offers its factory-refurbished GoPro HD Hero4 Silver Edition 1080p Action Camcorder, model no. CHDHY-401, for $199 with free shipping. That's $90 under the lowest total price we could find for a new one, although we saw a refurb for $20 less in November. 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.
