> So by making use of the information disparity, and manipulating the perception of the used market, it should be possible to keep prices artificially high. It seems like this would be really hard to pull off, though, because apparently they're simulateneously keeping prices artificially low. I can see them keeping the casual buyer and seller ignorant of each other's existence -- especially if they're fixing up the pianos and selling them as 'certified refurbished' (or whatever), so they're not simply buying low and selling the exact same product high. But wouldn't the whole thing crumble when a few enthusiasts got together and discussed their experiences as buyers and sellers -- or when a few sellers (whether through ignorance or knowledge) publically and successfully held out for higher prices?
