TECH: Overhead projectors

[GeorgeAnne Draper <GDRAPER@WYNNE1.CRSC.K12.AR.US>]

I am trying to put some consistency in the purchasing of overheads.
These are for classroom use,not for presentations.  We would like to
be able to order one type of bulb ...eventually. Our newer machines
are 3Ms and we like them.  What do you think about the best overhead
for regular classroom use?? Thanks for your help.
