Cheap RT73 based usb dongle TP-LINK TL-WN321G Wireless USB Adapter

The TP-LINK TL-WN321G Wireless USB Adapter gives you the flexibility to install the PC or notebook PC in the most convenient location available, without the cost of running network cables. Its auto-sensing capability allows high packet transfer up to 54Mbps for maximum throughput, or dynamic range shifting to lower speeds due to distance or operating limitations in an environment with a lot of electromagnetic interference. It can also interoperate with all the 11Mbps wireless (802.11b) products. Backtrack 4 supports this USB adapter out of the box (injection & frag), because in based on the RaLink RT73 chipset. My recomandation is to install the p_larbig 3.0.3 RT73 enchanced drivers.
