GoPro via eBay offers its factory-refurbished GoPro Hero3+ Silver Edition Waterproof Camcorder, model no. CHDHN-302, for $149 with free shipping. That's $51 under our December mention of a new unit and the lowest total price we've seen for this model in any condition. (It's currently $85 less than the best price we could find for a new one.) The camera features a housing that's waterproof up to 131 feet, up to 1080p video resolution at 60 fps, up to 10-megapixel photos at 10 fps, WiFi, and built-in microphone. A 1-year GoPro warranty applies.
