Hi dorsop, its more something depending about the mix of:
- your budget
- your artistical / technical needs
Essential questions are:
wich luminosity ( dont get down the 3000 lumens, be aware more far you are from the projection plane less light there is)
wich ratio of opening of the lens ( 1:1.2 / 1:2.5 aka 1m width is obtain at 1.2meter distance, or 2.5m distance)
wich nativ resolution of the matrix of the video projector ( are you displaying HD on one VP or a 1280*720 native matrix is enough ), wich changes really prices and offer. ( Talking about resolution )
are you on a fix install, if yes investissment should be done on reliable material ( Sanyo, Epson, Panasonic) with warranty of 5 years or 3 years included in price.
For myself i m working essentially with Sanyo, that have a real great quality of contrast and color.
Actually on little-middle projects, im using PLC-XU106, very versatile, good optical range ( despite this is a fix lens), low price (800euros without taxes) for a high luminosity. This show is touring a lot and no problem with it :( [http://vimeo.com/20212510 ](PLC-XU106](http://us.sanyo.com/Projectors-by-Market-Government-Meeting/PLC-XU106), very versatile, good optical range ( despite this is a fix lens), low price (800euros without taxes) for a high luminosity.

I m actually on creation on another project with the same VP in ceiling position , 45° angle ( fan is adjustable, depending the angle). I think its very interresting for wide panoramics with 2 or more VP.
If you are thinking of color nuances, you should better go to Panasonic, wich are more soft and more nuanced in their projection.
This question of the color is very important, as your result on your screen at work will be very transformed on projecting .
Contrasting the videoprojector a lot in order to fight with a luminuous environnement will enhance loose of details and nuanciesalso. There will be a great gain of lighting.
If you have a project in tints and nuances, you should first make a video demo of your artistical material, and make some tests in shops before buying material. This will affect a lot your result.
Personnaly i m creating materials with the lighting and color response of the videoprojector in situation, and not at home on a screen.
I know that my screen will give me nuances i will never have at the end by projection. But this a theatre/dance approach, not based of working with customers and building a project on computer previewing.
