Well, the only FS I have is from Novalogic, quite old, '98, and it is called MiG-29 Fulcrum. There are versions of F-16 and F-22. As a matter of fact, it is not ver realistic, but very easy to pick up, I learnt to take off and land without manuals in 2 hours of game.
It is also quite cheap (10 US$) and doesn't need a good computer to play. It runs better on win 95/98, though I have it functioning in Win XP, even though the mission editor doesn't function.
I don't know if you will be be able to get a copy... BTW, where are you from?
Hope to have helped,
Thomas
