I would not say that 3dsmax is harder then Blender. For me, it is aactually easier. There, I have 4 viewports (giving a view from the side, from above, from in front and in 3d - although this might be possible to adjust in Blender, too) making it easier to 'see' something (so where something actually is and to where you are moving it). Also, 3dsmax can be better controlled via mousethen Blender, while Blender is more focused on the keyboard (for example, I hate it to rotate the view via keyboard...). I really don't like the latter, but it might be a matter of taste. And yes, 3dsmax is quite expensive unless you have relations or luck or something. But you would need max 7 or 8 as newer versions don't work well with the nif plugins to my knowledge. Maybe you can find a cheap / used version somewhere.
