there's nothing 'mysterious' or confusing about reserve prices...they're just the minimum price a seller is willing to sell...i don't think its a waste of money, if you're putting something up for auction, good selling strategy is to start the asking low to attract attention, but with that, there's a chance, it may end low, so the reserve protects sellers. in my opinion, its better to reveal the reserve, i don't see any negetive implications from revealing it. it lets the buyer know exactly what to bid in order to win, and they may even choose to bid over the reserve in hopes of outbidding others. because auctions usually last five days or a weak, this gives the buyer lots of time to think about exactly how much they need to bid in order to possibly win your item. its a win win situation...
