Projector and Screen recommendations

Semi,
Interesting system!
I'm a tube guy too...with Oppo's 2 channel variable output into a 2 channel AES/Cary power amp. It has awesome sound on movies. I just need a projector/ screen system...now I'm thinking of one of Samsungs DLP projector HDTVs instead.
What does your system consist of?

Looks like I can get a Daylight B screen for under $200
Which entry prijector should I get?

Kirkus,
I want to mount the screen behind a window valance to pull down in front of a bank of windows, so when you say "you MUST use an angular-reflective screen" are you saying it must pull down and stablized on an angle in line w/ the projector or viewing? Or are you saying the screen is angular-reflective in design?

I can easily be satisfied with a 67"-80" screen w/ 12' viewing distance. Is this satisfactory and what do I need to look at in a projector for this size? I'm thinking of a coffee table projector is is ceiling mounted better?

No, I can't use blackout shades. Our HDTV sits there with good results. But we do have good heavy plantation blinds on the windows. If a projection system is not feesable I'm willing to get a plasma TV.

Thanx everyone.
There is some good info to get started.
Now I will have to research further and get prices.

Kirkus, thanks for your wealth of knowledge on screen choices. It will help. I will now have to research the apropriate projector to match a screen.

Drew, thanks for the info on directional lighting.
