Kevin; you bring up an interesting point. If you ordered a new one, then I'm guessing there may be a waiting period, perhaps not inconsiderable. I have no idea if they keep these in stock around the shop or how long it takes for them to make one or if there is a waiting list for one. So if you really need a rackmount power supply now, say if you're leaving to go on your winter/spring East Coast tour next week, well then a couple hundred dollars extra might be worth it. So if time is a consideration, perhaps a used DS-5R could indeed be worth more than a new one!
