TigerDirect offers the factory-refurbished Netgear 4-Port Powerline Ethernet Switch, model no. RB-XE104, for $22.99. With $2.29 for shipping, that’s $5 under last fall’s mention of a refurb and $44 less than the lowest total price we could find for a new one today. This plug-and-play Ethernet switch uses your existing electrical outlets to create a secure high speed building-wide network. It features an 85Mbps transfer rate. A 90-day Netgear warranty applies.
