If you are adding (reaping) components which total resources doesn't exceed the 1/3 of current value design you are actually paying less (20% less at least) than you would by building the damn thing.The only retrofit that cost more than buid is the Last one as the RW(SW) placement, cable and plating components cost 3*100K, 3*50K respectively which is quite more than 1/3 of Last design.
