I have a like new Nishida Radio Unisdisk Air c available with matching Toshiba FlashAir (16GB) SD Card as well as an SD Card Extension for mounting outside of the case for better WiFi signal. Firmware/CPLD are updated to the latest code and it is tested working great. I am unsure of the current value due to all of his products being discontinued. If interested please shoot me a PM and we can discuss. Shipping will be from SoCal, USA.
