I may be off my rocker here, but you (Darth) buy and sell gear all the time. I have never seen a 5pc collectors set in my area for near that price. I say buy them, set them up, tap on them a bit, give the lugs some love, either confirm what you already know about them sound wise or be surprised...then make some money for your efforts.
Better yet, record all the sets you have, even if only with an Phone and shut down the love/hate threads instantly. That seems worth the effort!
