I got my Sony 505 at:
http://www.bhphotovideo.com/
they had a demo version which about $240 US + $40 shipping to Australia.
The demo came in perfect condition and it was charged so I could use it straight away! Shipping was also super fast (I went with the cheapest option but it only took 6 days including weekend and 2 public holidays)
Very very happy with the service overall!
