    I bought an Ebbco for about $50 US in 1977, with which to
    teach myself celestial. I agree with George that you could
    go around the world with it. On a 26-foot boat the pitching
    of the platform will wipe out the accuracy advantages of a
    good sextant.
    However, I found the Ebbco very unpleasant to use, because
    it was easy to get sunlight in my eye around the filters,
    scattered from something. I also noticed that sunlight
    caused the index error to drift for about 30 minutes after
    taking it out of the box.
    Caveat:  I don't know the model of the Ebbco. It may be a
    cheaper one than those George described.
    I came upon a very nice brass sextant at an auction, with
    nobody else interested because it wasn't old enough (1958),
    so I haven't used the Ebbco since.
    A few years ago I tried a Davis Mk 10 on a trip from Nova
    Scotia to Maine, and found it much more comfortable to use
    than my memories of the Ebbco.
