Or, if you're a college student, you can get the student edition for free; it's fully functional but the catch is you can't sell what you make. You can get it through Autodesk. As for Blender, I don't know how well that coincides with Brawl Box and .dae files...
1. You don't have to be a college student
2. Blender doesn't work with importing.
Just clearing that up.
