TRENDnet TEG-S80G 8-Port Gigabit Switch for $19.99 shipped.  Here is a screenshot for your reference.  This is a gigabit Ethernet switch that goes up to 1000Mbps and not the typical 100Mbps switch.  It is part of TRENDnet's GREENnet line and adjusts voltage as needed to reduce power usage.  Most places have it for about $33.
