Most sellers on ebay know very little about the razors they sell, beyond 'some people pay money for such things'.
I've bought plenty of old razors in need of additional work (sometimes significant) for much more money than I could've bought a new razor, but that's because I find certain things very desirable and unavailable on the current production razors. And of course, I've also bought some junk that's no good for anything, and some for well below what they should cost compared to any new razor.

And there's absolutely nothing wrong with buying a brand new razor, virginity does seem to come at a premium, but there's never been a shortage of people willing to pay the price.
