I have the MARROW_SUN and it fits well and is very reasonably priced.
Here is a pic of me with it on and mind you, the ears are not attached and I thought the flair was nice.

I love the M_S. That doesn't go to say that the others are not good but I just wanted to chime in that the M_S was a well crafted and well shaped helmet if you are really looking.
As far as the cutting and sanding, it is all up to the buyer. M_S does trim and prime them if asked but it will cost to have him do that.
I went the cheaper route and bought the raw cast so I could do the work myself but I have seen the ones that he has cleaned up and primed and highly recommend them!
