mwave offers the TRENDnet GREENnet 16-Port Gigabit Ethernet Switch, model no. TEG-S16DG, for $79.99 with free shipping. That’s tied with our February mention as the lowest total price we could find, this time by $19. This switch claims to consume up to 70% less energy than the average switch by powering down Ethernet ports when they are unused or when the connected device is off. It features 32Gbps forwarding capacity, back pressure control for half-duplex mode, and more.
