Good advice from Apex...
I have progressed from FS '98 to FS 2000, to FS 2002, to FS 2004, and FSX...!
FS 2002 (and Pro) is an excellent Flight Sim, and will suit most "low end" hardware...with lots of Freeware scenery, objects, etc
The step up to FS 2004 brings much better default scenery, again with lots of add-on, freeware scenery, objects, etc, and is very slightly more demanding on computer hardware than FS 2002, but is well worth obtaining, and will give hours of pleasure, generally with no problems!
FS 2004 is still available in certain stores (do a search) and well worth snapping up!
...I thoroughly enjoy mine!.. [smiley=thumbsup.gif]..!
