It is worth reading a little on the different types of digital.
Here is the basic DLP site info
http://www.dlp.com/tech/what.aspx
The limitations of single chip are the available colours , Similar to my plasma in its available colours and you do notice this lack of colour gradient.
The single chip DLP has the unique ability to produce the "Rainbow effect"
, Not seen by all so well worth watching a full film. This effect can also cause the viewer to feel tired and so makes watching a film harder going - Not everyone feels this effect, Well worth taking the family to view a full film.
Make sure you sit at the distance you will view your own screen, Many digital demos sit the audience much further back than you would in your own room, this tends to hide "digital issues".
The 3 chip DLP design is in my opinion closer to the design of the CRT - Three separate colour optic engines , Of course the limitation is still that in DLP you still have only ONE light source and that is trying to create everything, And from experience the variation in lamp emissions in digitals is the largest let down. YES I totally agree that colour balance for a digital is very well spent money, Sadly the low lamp life and rapid deterioration of many digital lamps means that a "tune up" is frequently required to maintain good colour balance, And of course every new lamp means a tune up.
Only fair to mention that Xenon arc lamps produce a better white light and more consistent through their life span. These tend to generate more heat for lower output.
DLP Halo effect - YES it does exist with digital, reduced by use of a good velvet surround screen , For CRT LC lens system reduces the Halo effect.
What about LCD?
Here is a good comparison of DLP vs LCD
http://www.projectorpoint.co.uk/ProjectorLCDvsDLP.htm
LCD brighter and sharper - But in reality brightness in the domestic environment is not an issue, Sharper - Well in this case that is seen as a negative point as it highlights the "chicken wire" effect - Often a slight overall defocus is used to reduce this effect.
The best thing to happen in the digital revolution has been the invention of "
LCoS" based projection.
SXRD, D-ILA and HD-ILA
Silicon X-tal Reflective Display (SXRD) and Direct Drive Image Light Amplifier (D-ILA and HD-ILA) are proprietary
LCoS technologies from Sony and JVC respectively

Slightly more expensive but with that a step up in quality of image - Sadly Sony seemed to employ very relaxed quality control and this led to the main area of complaint - alignment issues. The JVC units seems to suffer from consistency of lamp quality.
I do hope that in time consistency of lamp quality will improve, For me that is the area that requires most development in digital projection.
I still prefer the image given by a CRT projector, Each person will have their own opinion on that. If it is image quality that is top of the list of "Must have" then for me CRT is still top of that list.
