Premium Travel Charger for Microsoft Zune 30GB Zune Scorpion 4GB / 8GB & Zune Dragon 80GB with IC Chip
Great accessory for the price.  Only difference I see with this generic Zune charger compared to one from Microsoft is that the Zune is unable to be turned off while charging.  It'll just be faded out while it charges...don't know why, but it just can't. Other than that it serves the same purpose.
