Unless you are talking about one of the 25 DP DLX Scout helmets, it would be a deal and worth it. For the regular version it is expensive and the helmet requires a lot of work to make it look good and keep from warping out of shape. Would definitely go for a fiberglass helmet myself... and MLC comes to mind. Altmanns also did a very acceptable Scout helmet, as well as KS - though... irrc, these are made in ABS plastic!?
Surely more will chime in.
Good luck with your armor... and your helmet hunt! :thumbsup
