Hi Bill!  Thanks for the projector information.  
I have a couple of questions:

- How would you define a large audience?  Is the typical stereo club
  of 40-50 max people included in this definition?

- Why does the TDC 116 have a need for frequent adjustments while the
  Twin Ektagraphic projectors do not (other than focus)?

Thanks!
