What is a really good, cheap flight simulator for Macintosh?

Im looking for a really fun Flight Simulator that is sort of cheap and can work on a Mac. Something like Flight Simulator X.



I don't really like the war type flying games, but more like Airline flying and private jet flying. Any help would be greatly appreciated.What is a really good, cheap flight simulator for Macintosh?
Most good games don't run well on Macs. My suggestion is to get a different computer if your interested in gaming. If you have a friend that knows how to build computers that's really the way to go. It's cheaper than buying from a brand name and parts are easier to replace.
