I think people on the list know your work and like me are thinking how the
heck are you going to scan that shape ! All the amazing geometric detail
etc. Perhaps what you need to scan are not your most complex parts?

I have done some scanning of small items with a David scanner (which HP
just bought). One was a piece of gold jewelry that was about 50 mm on a
side. I can't speak to the absolute accuracy but the trick was to spray it
with white spray. Welder developer works fine. It washes off the metal.
The David scanner is not fast and is more than your $1k budget though.

I wonder if anyone on the list has tried photogrammetry for small objects?
There is an article on it here.

If you have a high quality digital SLR camera you could try a demo of
photomodeler, photoscan or the like. This will only work if the object you
want to scan have surface texture. The point here is that if you already
own a high quality camera, you get to leverage that instead of rebuying
