When everyone had the "oversized" F/X helmet, it was highly sought after. Now there are several options on the ANH size ones. I do not see them as often as I once did. I think it is a pretty good helmet to troop in if you are looking for that and not worried about "ubber" accuracy. If you are wanting a display piece, I'd look for a GF, TE or a Master Replica that may be coming out here soon.
Just my opinion, let's see what everyone thinks coming up here on this.
