This was posted recently to OzBargain for $149. That deal is now marked expired, but it is now even cheaper, at $118.40. Shipping is $9.95, but "click and collect" is also available.
You can get plain Bluray players for much less, but the cheapest 3D player I could find on staticice was over $250, though I've seen 3d players for around $150 elsewhere. Google player found a cheaper player ($111) from overstock.com, but that needs a 110v power source, isn't new, and ships from the US.
It doesn't appear to have wifi, but has a network connection etc.
if it's the 5200 model, then it is WiFi..
I finally got to open my xmas pressie up last night and set it up
very quick setup for wifi and settings.. menu is great
and net tv is built in..
and it connects to my Anynet+ on my Samsung TV so it's great
the usb plays all the files i put through it so far
not bad.. but my wife paid $129 for it 2 weeks ago..
so this is a great price for a 3D model in deed
