I've seen several mentions of Gmax here...and you still can get a copy for it, but Autodesk has ceased it's "support" meaning there will no longer be newer versions coming out...however, I'm not sure if there is an exporter that has been made for the program. Gmax is a great tool, but is really limited, as it will not export to .3ds, or any other format other than it's proprietary format...unless someone has made an exporter for it.
You can download Gmax for FREE at this link: www.turbosquid.com/gmaxLike I said...it's not being upgraded, so you're stuck with Version 1.2 forever, but it's the same great modeling atmosphere as 3D Studio MAX,

it's exactly the same tools(but you can't render scenes) and it's free.
If there is an exporter for Gmax...i strongly believe we should push in that direction as TrueSpace is a thorn in any moddelers side. Caligari shouldn't be allowed to charge money for future versions of their software if it continues to be so...."inferior" to products like Max, Maya, and Cinema4D
I would stand to claim that 3D Studio MAX(or GMax) and Maya are probably the highest quality for doing any kind of modeling...plus they are the two best programs available...so if we can go in that direction I think it would be for the best of this community...
