I just bought the Kogan 4K TV.
Waiting for arrival, here in a month.

AU$999 + AU$209 (5yr warranty) + AU$36 (shipping) + $9 (insurance)
Closest competitor priced at $3,599.

Good things:
120Hz
USB 3.0 / MHL / Wifi
Recording 1TB support
Android OS (instead of "smart tv")

Bad things:
Edge-lit LED (not from panel)
Active 3D (passive is superior)
