The nicest one out there I ever knew of was the FS2000/2002 version done by www.carenado.com. However, they don't even list it on their website any longer. Considering their old FS2002 Archer worked fine in FS9 (with the exception of a missing prop), I assume the Saratoga would have worked okay, as well.
Perhaps they are working on an FS9 version? Wouldn't hurt to email them. - Matt D.
