Newegg offers the refurbished Logitech Z506 5.1-Channel Surround Sound Speaker System, model no. 980-000430, for $34.99 with free shipping. That's $3 under our refurb mention from last week and the lowest total price we've seen for this system. (It's also $19 below the best price we could find for a new one.) Features include 75 watts RMS power, a down-firing subwoofer, 45Hz to 20kHz frequency response, and 3.5mm audio input.

Note: A 90-day warranty applies, although it's unclear who backs it.
