    Re: horizon mirrors: was [NAV-L] Question about Davis Mk 25 sextant beam converger

     There may be two reasons why no one has bid on it. First, the BIN price is $475
    versus $510 new from Celestaire. Very little incentive for anyone to BuyItNow
    and get a used instrument, especially since that price is higher than it used to
     The opening bad price at $375 probably isn't bad, if there's no reserve price
    behind it. But part of the eBay bidding strategy is that people will wait until
    the last minute rather than bidding things up gradually, and since there aren't
    many sextant BUYERS out there anyway...It is possible that someone will try to
    buy it for $375 two minutes before the auction close. (And miss if someone else
    is in there at $400, 20% less than new.) At $375 I'd call it a very good chance
    to buy a good metal sextant. At $475...Absolutely not. And it may be that some
    buyers are simply offended to see it offered for a price that close to retail.
     The Astra enjoys a good reputation and with Ken's Celestaire (an excellent
    reputation) to back it, there's nothing wrong with it. I've used the Ares and
    Astra (both similar Chinese metal sextants) and both are indeed a big step up
    from plastic, and capable of taking you around the world. But at that price and
    performance point, there's a lot to choose from in used sextants (i.e. Tamaya,
    Freiberger) so buyers may be prefering to wait for a better instrument at the
    same price, or a better instrument at a slightly higher price.
     By comparison, I put my C&P Horizon Ultra up with a BIN of less than half of
    the new price. More than an Astra, yes. But I'll leave it to others to say which
    might be the better bargain for what purposes.
