mwave offers the refurbished TRENDnet 5-Port Ethernet Switch, model no. TE100-S5, for $6.99. With free shipping, that’s $6 under the lowest total price we could find for a new one, although we saw a refurb for $1 less in October. This Auto-MDIX switch features five 10/100 Ethernet ports.
A 1-year warranty applies, although it’s unclear who supports it.
