Mwave offers the PremierTek PowerLink 802.11n Wireless USB Adapter, model no. PT-H10DN-1W, for $22.99 with free shipping. That's tied with our mention from last week and the lowest total price we could find by $2. (For further comparison, we saw it for $2 less during Black Friday week.) Claiming an operating distance of up to 1,500 meters (0.93 miles), it features a max speed of 300Mbps, 5dBi dipole antenna, and support for WEP, WPA2, and WPA-PSK encryption.
