This was a fun project for me using Zbrush with Blender 3d.
Why the cheap price?
Well, it has exceptional textures, a rather nice form, but in all honesty this is an old model which was created with 'multires' in blender 3d. The main model (which the renders are taken from) has the multires applied, giving a very high polygon count, which may be undesirable to some people.
I have supplied another file which has active multires and lower poly count, which is unwrapped, but does not yet have materials or textures set. Between these two files, its possible for you to create any optimization you want.
