Hi Greg,

Well I am trying to get feed-back from colleagues with hands-on 
experience with 3D DLP as a support for teaching and/or small-group 
Please, could anyone answer my (practical) question regarding which 
beamer has worked best, in their hands, for a 30-50 people conference room.
Later on, after I've got an answer on that, then I will perhaps address 
a new question regarding glasses.
Many thanks in advance.


PS: Thanks Greg. May I say the actual spelling is "Bonne chance" as luck 
is a "feminine" word in French (with all due implications).
