I bought a new point and shoot camera at the end of last year to upgrade from what I had.  At the first airshow I went to this year I found that I didn't have enough zoom capability to get shots of anything in flight, and I have a hard time getting a picture that isn't blurry when trying to shoot a moving airplane.  
So, I'm back in the market again and I'm looking to have something decent before leaving for Thunder over Michigan.  I can't spend a ton of money and don't expect extreme professional results.  Does anybody have any recommendations for a decent camera in the $500-ish range?  I'm looking at this one:
