I am selling my Nanovision MIMO UM 710 USB 7" display. It's a great second display and can be used in portrait or landscape mode. I am getting a bigger second monitor so this one must go.
USB powered, plug and play. Windows 7 and Windows 8 automatically download drivers from Windows Update. Just open your Display Settings and get your desktop extended to the second monitor and there you go.
Asking price $95 (incl postage). I am in Johnsonville if you want to collect.
