Chromecast Ultra is my third Chromecast. It retails for US$69 (S$99). It doesn’t ship to Singapore directly, so you have to go through a freight forwarder like HopShopgo.
On 15th October 2014, Toshiba launched the new L9450 Series & L5450 Series for it’s television range that are powered by Android 4.4.2 (not Android TV). Note that the Android will not be upgradable and hence you will be stuck with it till the end-of-life of your television.
