This is something I've wondered about when it comes to buying on e-bay. Why would someone spend almost the same money for a used item that is no longer in production when they could spend almost the same amount and get something brand new with a warranty? I'm not talking about some rare hard to find item that might add sentimental value. For example, I saw a AF-S 80-200 f/2.8 that's currently at $1300. That makes no sense to me when you can get a new AF-S 70-200 f/2.8 VR for a few hundred dollars more AND a warranty on top of that. The extra range and VR would make it worthwhile. I know maybe a few hundred might be a lot for some but when buying optics of that level, if you're going to quibble over a few hundred, maybe one ought not to be spending the money in the first place. When you add the fact that the bidding doesn't end for another day and you know it's not going to stop at $1300, it makes even less sense. I attribute that to bidding fever. To me E-bay has been about getting bargains. I have to hand it to the seller though. If they can unload an item for almost the cost of a new one that's more advanced more power to them. I'd like to think I'm a wiser shopper though.
