I almost picked one up at Walmart the other day. It was assembled and damaged, and they would not discount it, so I said keep it. I did get a good look at it.
Not much different than the MR. With work, this helmet should be fine to troop in and would accompany approved stormtrooper kits. It will need some filling, sanding and repainting. The price is kind of high for the work involved, but it does have built-in sound.
