We are looking for an overhead projector to use with
an LCD display. The few spec sheets I've seen are all
for 3M models that seem very similar, yet I would think
that there should be:

  * some variation in optics. Are there models that could be 
  positioned closer to the screen?

  * some variation in brightness. Are there projector/screen
  combinations that perform better where brightness is 
  critical?

  * some variation in light path. Are there models that would
  work with a permanent wall or ceiling mount? When used with
  an LCD the display surface does not have to be accessible
  to the speaker.


Any A/V experts out there?
