I am not sure about the oculus for modelling. I have had the opportunity to try it ous because my work has one, and one of the projects I am currently involved in uses it. It was a very nice experience in the sense that it felt very intuitive and it was pretty ok for sculpting. However, it didnt have the full workflow, so I would expect som issues with importing /exporting from another 3d application like maya or blender og mudbox or whatever . On the other hand it is a great toy, so if you can afford one do go ahead :-)
