Best Buy offers the refurbished 2nd-generation Apple AirPort Express 802.11n Wireless Base Station, model no. MC414LL/A, for $49.99 with free shipping. That's tied with last month's mention and the lowest total in-stock price we could find for a refurb by $14. This device uses 802.11n to play iTunes over your wireless network to your home stereo, acts as a wireless router, and enables wireless USB printer sharing.
