Look for house-parts recycling centers in well-heeled zip codes. A growing number of them now stock gently used high-end appliances from the likes of Viking and Sub-Zero. "When a multimillionaire buys a house, he or she redoes the kitchen, and that usually means replacing the perfectly good appliances that the previous owner installed just a few years earlier," says Steve Feldman, president of the nonprofit salvager Green Demolitions, which has stores in Norwalk, Connecticut; Bethel, New York; and Honesdale, Pennsylvania. He has hundreds of ranges, cooktops, wine fridges, vent hoods, and warming drawers that have been donated by homeowners or dealers. Donors get a tax write-off, and you get a deep discount on the resale. Just keep in mind that these appliances come without warranties, so have them checked out—and possibly tuned up—by a repair pro. Still, if you're getting a nearly new Viking range for thousands less than retail, you'll come out way ahead.
