Hello, CK.  Have you looked at the WWW for these?  You might try B&H
(www.bhphoto.com)  in NYC which has a good online catalog.  Also,
during a recent conversation with a projector manufacturer rep, he
pointed out something which I hadn't thought of.  The projectors that
we are specing, like the ones you list below, are intended for
boardroom presentations for which they are on for a couple of hours at
a stretch.  On an exhibit floor they will be on for 8-10 hours at a
time, several days each week.  This manufacturer (who makes projectors
for commercial and other applications) claims that the lifecycle costs
of office projectors will be greater than a commercial projector, even
though the first cost will be higher for the latter.    He said that
the lcd components wear out, which I had not heard of before.  If you
want more info about this particular manufacturer, contact me off list.
  Anyway, let me know if you can  not find prices for these lamps on the
web, and I will see if I can help.

Good luck
