Ottol, if you want a free program you need to get gmax (but you'll need FS 2k2Pro for the gamepack).
If you can afford a few bucks, then FSDS2 is the one to have.

Isn't Gmax a more powerful tool if you know how to use it? It doesn't have everything (like a drop down list with stock animation names), but it does its job.
I use Gmax. I might have thought about FSDS2 but for CFS3 you need Gmax. Since I develop things for FS2002 and CFS3, just using Gmax I can do both.
