From an article at the time of the cancellation of the Comanche in 2004:
At a Pentagon news conference, senior Army leaders said they would propose to Congress that $14.6 billion earmarked to develop and build 121 Comanches between now and 2011 be used instead to buy 796 additional Black Hawk and other helicopters and to upgrade and modernize 1,400 helicopters already in the fleet.
That works out to $120 million apiece in 2004 dollars! Additionally, as mentioned previously, it was grossly overweight and could not do all of the missions without significant redesign. About the only place they could have cut the required weight was to scrap the ducted fan and revert to a conventional tail rotor. I am sure somewhere at Sikorsky there is a sketch of such a change.
