As far as being overpriced, I disagree with everyone here - and no, not because I have them... and I'm certainly not selling them so I have nothing to "gain"
As my dad always said, something is worth what another person is willing to pay for it. If people are paying those prices and demand outstrips supply - which is the case here - then they're worth those prices at the current time. As much as many of us here might get frustrated by ebay at times, it remains a free market and a good judge of "value" at any given point in time. Will they hold this value, go up or down? Well, the market will let us know and ebay is a HUUUGE part of that market - like it or not.
