You can make blender work it you don't mind doing a little hand work. The way I have done it in the past is export it as a NGON without welding the mesh. this removes the problems around the joins (as it isn't joining) but there are usually still some problems on rounded areas but If you go around the mesh and remove the small triangles you can get nice looking meshes out of it. it's not ideal as it would be nice if you could just do an import and be done but it is free And I have had to work out making MAX work nicely with MOI as well so....
