well i have all but the F-117 but im interested.
With the wilco A400 its very nice, lovely to fly and very realistic. A worthwhile addon, bt only if youre interested in that area of flying and if youre going to fly it.
The A-10 is a winner, gourgous model and paints, handles very well, one of the best i know of, a definate!!
Seahawk and boxer can be rather hard on frames and from what ive heard of FSX you dont get al that many frames anyway so be cautious and id say if youre using with FSX you might get a hard drop in frames, you definately do in FS9!!
And the 747 is very nice, ultra realistic, so if you dont have the patience for a very large learning curve to lean all the instruments its not for you, i know i made that mistake so its not one i fly all too often

hope this helps
cheers
