mwave offers the Powerlink 802.11n Wireless 4-Port Router, model no. PL-APN, for $47.99 with free shipping. That's $9 under our mention from a week ago and the lowest total price we could find now by $16. Claiming an operating distance of up to 2,000 meters — yep, that's 1.24 miles — it features a maximum speed of 300Mbps, 5dBi dipole antennas, and support for WEP and WPA2 encryption.

Update: The price has increased to $48.99; however, it now includes a $2 mwave credit. Assuming you use the credit, the net price has dropped by a buck.
