I use Fragmosoft's Fragmotion. As mainly a coder, I don't have time to learn any in-depth (and often over complicated - for a coder at least

) 3D editors like Maya or XSI. Fragmotion is extremely intuitive and therefor I found it easy to pick up quickly. It's quite powerful (enough for game modeling, including animation). It can export to many formats and I particularly like it, as what you see in Fragmotion, you see in TV3D (if you have the lights setup ok). The UV mapper has changed from V1.0 but it was just a case of relearning that, although I often revert to V1.0 for texturing as the system was more straightforward for me. There is a free version (smiley does become annoying after a bit), but it's quite cheap at 50 USD atm I think.
