Has the market arrived at a general currant-per-credit value for upgraded furniture? I've got a spare upgraded door (Sturdy Stronghold - 25 credits) to dispose of, and I have no idea how much to post it for at auction.
I'd agree; the going rate generally ranges from 1k to 2k currants per credit. I prefer to sell (and buy) at 1k per, +2-5k to cover the cost of the base item, auction tax, and bonus munnies/tip/whatever. That's just me, though.
