GoPro via eBay offers its factory-refurbished GoPro Hero3+ Silver Edition Waterproof Camcorder, model no. CHDHN-302, for $149.99 plus $9.63 for shipping. That's at least $66 less than you'd pay for a new unit, although we saw a refurb for $11 less last week. 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.
