Elgato Thunderbolt Dock for $135
It’s not Thunderbolt 2 like the OWC Thunderbolt 2 Dock, but OWC has the Elgato Thunderbolt Dock at $135 ($115 off). It makes a fine unit for many purposes (features two Thunderbolt and three USB 3.0 ports, built-in HDMI and Gigabit Ethernet, as well as separate microphone input and audio output).
