I was searching around for some 3d modeling applications, and came across this one, http://repix.com/px.html, which is only $49. It supports exporting to X format, and importing from a variety of formats (I was looking for 3DMF import support because I have adobe dimensions which exports to 3dMF, and is halfway decent for creating 3d objects - certainly doesn't compare with the real 3d programs, but it's good enough for me).
