On clearance at Supercheap Auto for $269.99. TheGoodGuys are currently selling the same TV but with a DVD Player for $369.
Powered by Android TV, with Google playstore and built in Chromecast.
Has pretty good reviews on TheGoodGuys and Supercheap Auto's website.
Only downside is that it's not 4K, but it's still decently priced for a solid 1080p Smart TV with Android TV and many features.
