The thing is, people who look for used entry to mid-range gear usually don't have a lot of money and often have to scrap together just enough to buy an item. So for them a $50-100 discount is totally worth it. Not only that but if you buy a used Valhalla 2 for $300 and you feel like selling it in a few months, you can sell it for about as much as you bought it since you bought it used.
My issue is with the sellers, not the buyers ... but all the more reason for them not to entertain such high prices for used gear.
Each to their own though ... I have no issue with people trying to get as much as they can out of their items - just my perspective is that used items need to be a significant discount to be worth bothering with. And selling used items at, or for more than new, prices is just silly.
