OK, so this keeps coming up and I see links with with crazy prices for something that is not.
Also, stay AWAY from goggles, it screws up your head when you fly, looking at a small monitor is so much better.
So from a major company you can get this RTF (ready to fly) and just add the monitor of your choice. Not cheap, but not several K either.
The 350 quad from Horizon goes for $900 street price. Plus you can get spare parts at almost any Hobby Shop or online from US companies.

They also sell this without a camera or transmitter if want to upgrade or have GoPro type camera already.
There is also a optional fitted case and you can upgrade the transmitter for more range and more abilities with the camera in flight.
For a monitor, about the best I have found is from Hobbyking. It is a 7 inch with 5.8ghz reception and touch screen. $140
