    Good navigation is based on competency via several different methods.
    Lu described this as his "alternative method" of redundancy.
    Both reliability and redundancy are needed, as mentioned.
    
    Thinking about how I would buy navigation gear, I made the following
    lists.  I chose
    West Marine because I know that they have most of these things.  I
    would in practice
    shop around, use Froogle, check out defender.com, celestaire.com, and
    other places
    before buying.
    
    If I had $1,000 to spend on navigation gear at West Marine, I would buy:
    
      $300 - Garmin GPSmap 76 Handheld GPS (primary)
      $100 - Garmin eTrex Handheld GPS (backup)
      $145 - Davis Instruments Mark 15 Sextant
        $9 - Casio FX-260 solar scientific calculator (at Amazon.com)
        $9 - Casio FX-260 solar scientific calculator (at Amazon.com)

       $43 - Bowditch American Practical Navigator book (at Amazon.com)

        $7 - Dockmanship by David Owen Bell

      $510 - Astra IIIb Sextant

    The actual setup on my Tollycraft 26 was remarkably close to this
    last $5,000 setup.
    
    If you could double your budget again to $10K I'd add a laptop with
    electronic charting, another radar, and make the backup sextant
    metal, and so on...
    
    I really hate plastic sextants but I was not able to justify
    excluding a couple of good GPSes in order to buy a metal sextant for
    the $1,000 group.
    
    I like Astra IIIb sextants (I own one), but I really like the Tamaya
    Jupiter sextant, probably the best sextant that you can buy new today
    now that C. Plath is out of business...
    
    Other ideas about how you would really spend your dollars are
    welcomed... all of my prices are rounded to the nearest dollar and
    I'm ignoring tax, consumables like batteries, but I am really trying
    to stay under budget and I looked up all of the prices on
    www.westmarine.com and www.amazon.com.
