Newegg offers the Netgear N300 802.11n Essentials Edition WiFi Range Extender, model no. EX2700, for $38.99. Coupon code "EMCANNA54" cuts it to $29.99. With 99 cents for shipping, that's that lowest total price we could find by $8, although we saw it for a buck less last month. It supports 300 Mbps transfer speeds, is compatible with any wireless router, and plugs directly into a power outlet.
