The shape, position, and intermittent appearance suggests a
mirror-flipping
problem.

Remember the image is upside down in the camera.

A mirror problem seems about right. I remember the camera sounding
funky during the shot. Something sounded prolonged and it was
probably the mirror taking too long to flip up. Through the black
band, you can still see part of the image, suggesting that the
obstruction was only in the way for part of the exposure.

I tried to replicate it last night but couldn't get it to do it again

Yeah, but what happens if it starts happening again when you really,
REALLY want to get a good shot?

Which brings up a question.. Most cameras have shutters that are rated
for X number of pictures.. I assume most people who've owned cameras for
a bit have gone past this number? Is this something that can simply be
replaced by techs? I assume you can replace *anything* on a camera, but
does the procedure cost outweigh the possibility of simply moving up in
model?

I've not had to take my D70 in for servicing yet so I'm not sure on the
pricings for various procedures.

AFAIK there isn't a specific rating for the D70.
There seems to be an expectation that shutter life is in the range
50,000-100,000 actuations.
It will almost certainly cost more to repair a shutter than the camera
body is worth.


I don't know about the Nikon's, but I did a search on Canon 10d/20d shutter
replacements and they seem to be in the $150-200 range. I would think a
Nikon D70 repair is around the same price and isn't a good working one worth
more than that used?

50,000 exposures is a lot. I'm guessing that a "keen amateur" might
typically shoot something like 5-10,000 exposures a year, many casual
users much less than that.
My guess would be that shutter failures in amateur dslrs would also be
from dirt/dust/foreign object in the shutter, or accidental abuse rather
than mechanical wear and tear.
There was a D70 user in the UK posting on DPReview who "used up" cameras
very fast. For some inexplicable reason, he took many thousands of photos
of handbag-sized dogs. I think he "averaged" just over 100,000 exposures
per D70 body, and moved on to D2x bodies on the theory that the longer
shutter life and possibility to replace the shutters made the economics
viable.
You needed to see his portfolio to see that eccentric englishmen still
truly exist in the 21st century.
