I have seen an alternative to the complete LCD Projector.  It is a projection
screen that looks just like the LCD screen on a laptop, except that it has
glass on both sides.  It sits on top of one of those overhead transparency
projectors (transmission only, not reflection).  Overhead projectors can
be rented most places that rent lecture halls, and you don't have to lug
around the heavy light box and fan.

I have seen prices varying from $6,995.00 CDN for a new, color SVGA model
with fan for use with up to 5 or 6 KW projectors (comparable to a movie
theater projector) to $35.00 CDN for used, surplus, Apple monochrome
rated, I think, up to only 600 W (no fan).

You might want to start with a cheaper monochrome unit (typically
about  $100.00 surplus), to try things out.  If you are pressed to make a
decision, it would also give you time to shop around for something better.
It would be good for text and useful as a backup in event of disaster -
after all, these things ARE made of glass.

I have seen one advertisement for a laptop with the light/back of its
LCD removable for use with overhead projectors, but I suspect that it
is a poor compromise.

I hope this proves useful, and not just several more things to complicate
your decision.
