I second that caution.  The panels require such special conditions to
give a good image that they are essentially not useful in a dynamic
classroom environment.  Ours sits in its case and we use a couple of TVs
to get a clear, bright, useful picture.

Some of the new devices that produce computer pictures on TVs are
inexpensive and make a very nice picture ...  with an Averkey3 ($300)
and a Snappy ($200) and a good TV, you can do some remarkably powerful
things in class -- including capturing any image (like from a videotape
or Web page) for future presentation.

The projectors, however, give a nice, bright, large image.

Cheers,

Rick
