Mwave offers the PowerLink 150Mbps 802.11n Wireless USB 2.0 Adapter, model no. PL-14N, for $19.99 with free shipping. (Premiertek via eBay offers it for the same price.) That's tied with our mention from two week's ago and the lowest total price we could find by $5. It features a max speed of 150Mbps, dual 7dBi dipole antennae, operating distance of up to one mile, purported 6x signal strength, and support for WEP, WPA2, and WPA-PSK encryption. Deal ends January 18.
