Projector - Total cost of ownership
We are currently looking at projectors for a new build. I am trying to do a TCO exercise comparing both LED Projectors such as Casio XJ-ST145 vs a Promethean DLP Projector.
Obviously Casio is alot more expensive than the DLP but has the benefit of not needing replacements lamps. Neither require filter cleaning but how often should a projector be serviced? and would this differ between the two?
The only benefit seems to be the lamp repalcement, but I would expect only to replace the lamp once or maybe twice over of a 5 year period which does not justify the extra cost.
How would the image degradation over 5 years compare for these two devices? Casio claims to keep keep a consistent image quality but as I have never had one I wouldn't know for sure.
Any infor to help with the decision or TCO would be great.
