wings3d rocks. It has all the functionality of Nendo and now they are currently adding in a lot of the modeling tools of Mirai. It is almost at 1.0 now and it has a few plug-in developers for it already. My current workflow is wings3d -> amapi 6.0 (for the awesome smoothing) -> carrara for texturing and rendering.
