All digital sets (LCD, DLP, LCOS (D-ILA), require lamp replacement from time to time. It can be expensive. Plasmas don't have that problem but do have other issues, which are becoming less of
an issue as they get better.
Got the room for a front projection setup?
I run one of these:
194 pounds, about $45,000 at full retail, on a screen eight feet wide. (Will handle a 10 foot
wide screen but I choose to accept a "smaller" 8 foot wide screen.
Not the newest technology, and some tweaking is required on occasion, but the picture quality
tramples the best digital projectors into the dirt. The basis for comparison with suitably high
quality sources is to compare the image to the original film.
I deal in these units via the surplus market. I have several related models in stock and
prices start below 1000 dollars.
This model is still being made new. (Video Display Corporation Marquee 9500LC)
If you're a perfectionist, CRT projection is the only way to go. And the life of the CRTs is over
10,000 hours. No lamps to change.
Being CRT based, there is no "native resolution". They handle any resolution with equal ease,
from plain old regular NTSC tv (640x480, roughly) to 2048x1536, and beyond, to 2500x2000.
With no pixel structure.
