Do you transmitter/receiver work on 2.4GHz? If so, then stay away from a video system that works on 2.4Ghz. I am not sure what is allowed in your country, I think 900MHz shouldn't be a problem. I think only some Spektrum sets working on 2.4GHz have problems with 900MHz.

You have several systems to chose from, here is one for just a tad over US$ 100 + shipping: http://www.hobbyking.com/hobbyking/s...dProduct=13443

Almost everything is included, a transmitter, reciever, ntsc camera, antenna's. Only thing is that you need a wall-converter because the adapter for the receiver has European plugs. You might want to add a 3s lipo batteries  for the receiver (2000mAh or more, it doesn't need to fly so it can be heavy) and for the transmitter (~500mAh)

If you have questions, please ask. Will keep an eye on this thread.
