Kogan Technologies - 66cm lcd tv with built in dvd player and usb support - $499 + Buckscoop Cashbac
The Kogan PRO26 is very versatile and can be easily moved from room to room. It's perfect for a big bedroom TV and is large enough to be the main TV in the house. It has the ability to play video and photos straight from a USB stick, as well as a built in DVD player and HD digital tuner - this TV has it all!"
Thinking about getting one of these for the kid's games room. Includes built in side loading DVD player plus plays movies (divx/avi)/music/photos from usb drives. Not a huge fan of all-in-one devices, but then again it should be easy for the kids to use so require less parental guidance - which is a good thing (within reason, of course!)
If you don't care about the dvd player & usb media support, then they have other units - for example an extra $100 will get you a 66cm led tv or a 80cm full hd tv (although frankly 1080i is generally fine for anything smaller than 127cm/50inch).
