Some great pictures, I went to the paris airshow this year, but I'm keeping an eye out for other more display based shows like this one, great displays and even more fun when taking pictures of it all.
I agree to an extent about the 20D, and I managed to pick up a 40D for £375 second hand recently,and I'm not regretting it. Was only a £70 upgrade by the time I sold the 30D.
