I agree Chinaman, there is definately signs of improvement and subsequently change in reputation and then sales follow.

I did not realise it was as big as 10,000 exported by the top 4 - this must mean about 13,000-15,000 total and at a rate which is growing by around 50% a year! How did you come across this 10k number - do organisations such as CITA provide these figures or something, or do these particular companies state it on their website?
