Sounds good to me.

Well, I certainly don't know more than the Master of Stereo Projection.
I am just a humble student...  I do not have much hands-on experience
in stereo projection... and no experience with large audiences.  I have
only used a TDC 116 projector and have not experienced the misalignment
problems that you mentioned, in correctly mounted slides, projected
in a 70 in. screen.  I believe that people tend to abuse the TDC's
adjustments thinking that they must be used since they are available
for things like horizontal adjustment to eliminate ghosting from slide
to slide.  I avoid such practices.... And, of course, with twin 
projectors these adjustments are not easy.  

For a club level (50 people or less) the TDC seems acceptable to me.  
During the last NSA convention I was impressed by the performance of the 
Brackett Fader.  In my mind, an experienced operator can use the Brackett 
projectors to achieve the performance of the twin Ektagraphics for a
large audience.  Which is a sign of relief for me because I do plan to 
continue with my 41x101 mm mounting for some years to come.  Of course,
it would be nice to have an automatic dissolve 41x101 projector with 
autofocus... (something to dream about)
