How about opinions?
1) The lifetime of a product has three phases:
a) Early life, during which "infant mortality" failures
can occur. These include early failures of transistors
or more complex chips from weak wire bonds, cracks in
the chip which propagate into the active areas, or just
poor solder joints elsewhere in the equipment.
b) Main life -- failure rate is extremely low.
c) End of life -- things are starting to wear out, and
failures (especially mechanical ones) become more frequent
2) In my opinion, the 1 year warranty will cover the "infant
mortality" failure period.
3) Also in my opinion, the three year extended warranty will
expire *well* before the "end of life" period arrives.
4) Of course, this does not mean that you *will* not have a
failure in the "main life" period. I consider it quite
unlikely, but some do happen. How unlucky do you feel?
5) Put a tether on the protective cover over the image display
screen. The screen is fragile, and *very* expensive to replace,
so you want to keep it covered.
I suspect that the extended warranty does not cover a broken
display if it is broken from impact with a belt buckle or the
like. If it remains intact, and just stops functioning, that
would be a different matter. In any case -- I would rather
protect it than to pay extra for a warranty which *might* cover
The protective cover tends to hook on belts and such and pop
off. I lost the original one (it popped off during a hamfest,
when I was walking around a lot, looking at things, and I could
not locate it, even after retracing my steps carefully). It
took over a week to get a replacement. I immediately made a
tether for the replacement, which runs from the small hole near
the left bottom of the cover to the attachment of the left-hand
end of the neck strap to the camera. It has caught and saved
the protective cover at least three times since I installed it.
So -- *I* did not buy the extended warranty. I have Nikon F
cameras still in perfect working order, so I expect a good lifetime on
the D70. I *may* be proven wrong, but you have my opinions. The D70 is
mechanically simpler than the Nikon-F, with no film transport mechanism
to fail -- though it does have the motor connection to the lens focus
Also, I believe that the shutter is not as highly stressed, as
the mechanical shutter only has to uncover the entire focal plane before
the electro-optical shutter does the real exposure control, so it does
not have to work over as wide a range of speeds.
