Jake, I am going to try some "tough love" on you, so my reply to *what and how you posted* is going to seem harsh.

#1 - You "want to find a job" in the Game Development field, but don't know what "advanced modelling programs" there are?   Furthermore, you post this in a *specific game* board of a *specific modelling program*  Forum.  Yes, Anim8Tor doesn't "run" many of the models in turbosquid, but guess what, the model description themselves mention what program(s) they were made with, so that gives you a clue.

Just look at the various boards here in these forums, and you have an idea of many better modelling programs

The industry standard is 3DSMax, currently in version 9.   (http://www.autodesk.com)

Then there's Rhino, Maya, .....  What I was trying to say is that the different turbosquid forums are mainly for the major modelling programs in the industry. 

If you're looking for a job in the gaming industry, learning 3DSMax is practically a necessity.  If you currently cannot afford a US3500+ program, gmax, available as a download from turbosquid.com/gmax, is a cheap (as in free) alternative.  The caveat is that you can't export (easily) your models from gmax to other than a game that supports gmax.

Blender is another free, reasonably full featured, modelling program and quasi-gaming platform.
