Nice review. You hit the nail on the head too about the price putting people off. While I am a WW1 fan and game 1914 a lot with minis, I won't be paying that much money(not even including postage) for a boardgame. Also a turnoff for me is the sheer size of the maps, taking up more space than I have.
Oh and one little point - while I wasn't a member of their group back then, I know a few gamers who completed 3 or 4 full games of DNO back in the days. They still talk about it fondly.
