I like the economy article. I've always favored having merchants pay less than 50% market value for magic items. I use the used book store method for determining what you can get for an item. If a merchant can sell an item for X gp, he will give you 1/2 X gp in trade or 1/4 X gp in coin. The assumption was that the merchant might have to hold onto an item for a long time before he can sell it, so he has to keep his profit margins high. 1/5 market value is only a little less than the 1/4 I was giving.
I have allowed (and will continue to allow) good merchanting skills (probably Diplomacy in 4e) to provide a bonus to the percentage the party can get from an item, and a discount on what they want to purchase.
I've never been too concerned with how much money the characters have, since I limit the access to magic item merchants. Usually I determine what each merchant has available. The characters interact with the NPCs to find out what's available where. I also change the stock available between visits to simulate the merchant selling some items and acquiring others.
At first I hated the concept of residuum, but then I realized that it was just the name I hated. I liked the idea of disenchanting magic items when I first saw it in the artificer class. I'll just change the name. I can't decide on numina or mana, but it will probably be one of those.
