Al, everything any military around the world purchases is paid for by regular citizens, by taxpayers like you and me. It is therefore 100% legitimate to question pricing of products sold to the military, in fact pricing of such items should be analyzed and questioned even more than "normal" products sold on the civil market. No consumer must buy them after all, but we are all forced to pay for the things our military purchases.
Are the prices of Surefire lights reasonable? IMHO, some are, some are not. The C2 for example seems to be okay, the Kroma on the other hand is totally over the top. You get a Luxeon III and 16 3mm LEDs, each with 2 levels and current regulation for $300? Then the people in Denmark who make the Wiseled Tactical must be masters of efficiency, since for ~$470, you get 7 (!) K2 Luxeons with current regulation, 12 levels, strobe, SOS, a 53Wh Li-Ion battery, all of it in an ultra-tough aluminum body with awesome magnetic switches, dive rated to 300 feet. I like the Kroma very much, but when I received the Wiseled Tactical, I once again realized how totally off some of Surefire's prices are. If Surefire were able to produce a light like the Tactical, it would cost at least $2000, probably more.
As for the Beast 2, I never had the opportunity to test one, I will therefore not comment on its price.
