I was super happy to find a coupon I had to comic shop that happened to carry one still and I got it for $315 +tax with my coupon!
I think the value of it is only measured by what it's worth to you. If you're buying only to sell it later then you might be disappointed. Some items have truly skyrocketed in value, but I try not to think of that anymore. It's more than 90% of the time proved to be a loss on my end
Perhaps the economy right now has a lot to do with the going prices of some of this stuff too.
