It has been said time and time again on the official Eberron boards that the warforged with adamantine body actually don't have adamantine plating on their bodies which can be salvaged.
Officially, Adamantine 'forged are composed of a adamantine armor composite, which is a mixture of adamantine and other alloys. Assuming one had the patience and the equipment to try to extract the adamantine out of the composite mixture, the amount of actual adamantine is very small (about 1 lb, if I recall correctly).
Of course, your campaign and your DM may decide otherwise. Rule 0 is always trump.
The designer did some acutal numbers in his FAQ thread for the cost of stripping and smelting the 1 lb of admantine in a warforged body. It turned out to be on the high side, but not unreasonable. The biggest obstacales was to find the specialized forge and black (silver?) smith who could, and would, do the job.
As in all things related to specialzed skills, a GM stuck with the "adamantine" plate theory could just have the smith price the deal out of reach of the PCs pocket books, or say the total effort only gave them a discount on such armor.
"Hey, you getting your fancy plate mail for 20 percent off, that's better than retail."
On the other end, it's black mail parts, which means the guy supplying the goods gets the raw end of the deal and the middle man reaps in the profit. (Drug dealers, no poppy seed farmers make the profit.) If the adamantine smiths in town refuse to pay more than xxx, then tough.
Long story short, the DMG's numbers are set for a generic fantasy world. We've already seen that population/class ratios are different, so the GM needs to keep in mind that supply and demand in certain materials may be different as well.
