I have the inexpensive Davis and I have not been impressed. Screws have
fallen out of the mirror holder, leaving it unusable. Even before this, its
accuracy was quite poor.
If you think you are going to seriously want to do celestial nav and have it
as a backup (or primary!) source of position for a major ocean passage,
treat yourself to the Astra IIIb for $450. It is all metal and will delight
you far more than plastic will. I did this and it helped me get over the
hump of just toying around with celestial to becoming really dedicated and
serious about learning how to use a sextant.
Or look around for a good used sextant. You can often find other metal
sextants in the $200-$500 range if you look for a few months, or try
www.ebay.com.
Spending MORE than $500 for a sextant doesn't buy you much, but I think
every dollar spent up to around $500 is worth it.

Actually, imho, the Davis (either model) makes a good learning instrument
(especially teaches adjustment and the need to check prior to use) and when
you
move on to a metal instrument, makes an excellent backup
