Hi Tim,
Sounds like your putting together quite a nice set-up
As far as front projector go...
Beyond the picture, the inputs and...
the Ouh! Aah ! factors
(which are often linked to the price tag)
many little aspects are often forgotten
-lamp life and replacement cost
-fan noise during operation
-the right inputs for you
-That damn HDCP compliancy thingy
I would also recommend you look at multi-media PC projectors as well as home theater ones.
their costs are often much lower and they can handle most resolutions
I truly love my
Optoma ...
it was cheaper than a huge plasma...
I presentely have 86 inches diagonnally
and moving the TV will never hurt again...
this one might be a contender for you to look at...
my local Optoma guy has been comparing it to much more expensive models
(it's even 1080p ready)
as far as screens go I believe that it depends on your projector and...HIC! your budget
some Stewart ones are real nice
I settled for Draper at a much smaller price...
once again don't overlook the not so obvious...
-Cleaning !
(glass bead I hear are a pain to wash)
-viewing angle (If you have a wide room with seating on the sides, some screens could leave you disapointed...
Lastly...Don't forget that you'll have to run at least two wires to your projector from your 990 to go all out....
one for digital(DVI or HDMI) and one for analog (component, s-video or composite)
Best wishes !
Merry Christmas !
