Will that be enough to have proper picture placement?
Like Sam mentioned, you face compromises with all of the options - only you can decide which compromise is the least objectionable.
In terms of placement issues for the DLP projector, I will add that more than likely, you will need to "raise" the projector, rather than lower it. DLPs tend to have large offset parameters - which dictate how far outside
the image area the lens needs to be. If the top of the screen is 18" from the ceiling, then the projector may need to be only 6 or 8" from the ceiling (those are total guess numbers, BTW).
For what it's worth, my Mitsubishi projector is a DLP (720p) and my basement ceiling is on the low side (7' 8" I believe). Even with as "flush" a mount as I could produce with my projector, the image was too low on my wall (the bottom was only about 12" off the floor).
I wound up tilting the projector up slightly and using digital keystoning to correct the trapezoidal image.
Some image purists around here will say that using ANY keystoning is "the absolute worst thing you can do to a projected image" and "what's the point, why not just use VGA" and "the world's going to end", and yadda yadda yadda. Well, maybe not the last one, but a few have gotten close...
Personally, I am not able to discern any image degradation and have had several HT enthusiasts remark on the image clarity (they did not know about the keystoning), so take that as you will.
If you buy from a place with a good return policy, you can always try one and if it won't work in your space, return it and try another. You won't need a screen to determine whether or not it will "work" in your room.
