Refurb GoPro HERO5 Session | $170 | eBay

Despite its tiny size, the GoPro HERO5 Session includes 4K recording and voice commands just like its bigger sibling (though obviously, it lacks a touchscreen), and you can get a refurb from GoPro’s official eBay storefront for just $170 today. That’s a relatively modest $30 less than buying it new, but you get the exact same manufacturer warranty, so I’d say it’s $30 well saved.
