This migth sounds odd. but i have chosen another way... its not the bests. but i works for me... i used a hell of alot momon to get my self a camara with enough magapix. (15mgpix minimum is minimum for this) made a ligth room (white romme with alot of dim ligths in all directions. and photographed the maps. this removes one problem. but creates another... you simply cant get a camara with a resolution high enough to compeat with a good scanner.
