Fry's Electronics offers the EnGenius ERB9250 300 Mbps 802.11n Wireless Repeater and Range Extender for $19.99 plus $5.99 for shipping. That's the lowest total price we could find by $4, although we saw it for $6 less last month. This 2.4GHz repeater expands the number of users and devices that can access an existing wireless network.
