Hi
I agree with Naples.
I have a Sony P71 3.2m at the time it was £300 but i believe they are around £250 now.
I bought it with the intention to use when flying, the camera is very good and relatively small, so it wont disturb me too much if all of a sudden i want to take a picture in the cockpit etc...
If you want to see some examples of the quality of the image, just let me know, and ill send you some links of pictures that i took ( Aviation related ).
