[filmscanners] LS-8000 glass holders, was My Public Apology

Looking at the LS-8000 help files it appears only the single frame rotating
glass holder comes with overlay spacers?  As I work with the LS-8000 I see
the DOF is indeed limited as others have noted, and think the glass holder
is a good accessory for critical scans, but the damn thing retails for
$350:(

Making spacers isn't difficult (black "craft" paper is sufficient), and it
keeps contact pressure low where (and if) the base side touches glass.  This
review goes into some detail about the holders and use:
