Buy.com offers the IOGEAR 802.11n Wireless Adapter, model no. GWU627, for $24.99 with free shipping. (Amazon charges the same for its Prime members or with orders over $25.) That's the lowest total price we could find by $5, although we saw it for a buck less last month. It's designed for use with Ethernet-equipped TVs, Blu-ray players, gaming systems, and more and features speeds of up to 150Mbps, 64-bit and 128-bit WEP encryption, USB connectivity, and more.
