Thanks for the responses to my x-ray question.  I need to clarify
my question:

I'm not at all concerned with resolution.  The images I'm scanning
are not bone/tissue, but pictures of a gel made for DNA sequencing
(a bunch of little dark lines).  I think 200dpi with 64 grey levels 
would be more than sufficient.

My concern is light source.  If scanners (and remember I know nothing
about scanners :-) have an internal light source, would that interfere
with an image that was being lit from behind?

Thanks again,
