				Hi, 
I want to make a 2d mapping on a 3d surface wich 
projector I need a DLP or a LCD. Some people tell me that you can only make this with a DLP but others people tell me that Benq DLP projectors are cheap and they break easily so I don't know what to buy an I very hesitate.
The style of 2d mapping on a 3d surface I want to make:

				you can make any kind of projection with both types of projector,
dlp projectors have a higher contrast ratio, deeper black, but they create the colors with a spinning color wheel, what makes them flicker for my eye.
lcd projectors work kinda like your lcd tv with a tiny lcd panel, with light shining thru creating colors.

				You can make this type of mapping with either LCD or DLP. They both have their advantages and disadvantages (
http://www.projectorcentral.com/lcd_dlp.htm) but the skinny for me is that DLP projectors have better video black and LCD projectors have better color saturation. 
I'd be more concerned with lensing and brightness than LCD vs DLP if I were you but DLP will be nice for this kind of application because you'll be in a dark room with no lighting to compete against so having good video black will give you better transitions. Take a look at the video you sent and you can really see the video black at the beginning.

				Because my main goal is to project VJclips from Beeple 
http://www.beeple-crap.com/vjclips.php and his videoclips have a lot of black so I very hesitate and the problem for DLP 
projector: the rainbow effect...(spinning color wheel) make me hesitate a lot. I have some advices from some people that tell me don't buy DLP projectors they are cheap and break easily (BENQ projectors etc.)
 So I need more feedback my budget for this 
projector is maximum 600$ CAN with taxes. I know that 3000 Lumens is the minimum for mapping and I need high contrast. But I not know more than that. If someone who know more than me in the projectors could 
help me to chose the good one it will be great but thanks for your replys.

Don't confuse DLP and cheap consumer grade projectors. Some of the best (and most expensive) projectors on the market are DLP units.

That depends of the environment and the overall size of your mapping. If you map on a few boxes in a dark room like the video you shared you can probably have less than 3K and be OK. 
Why don't you give us the details of your installation such as:
- Overall size of mapping
 Distance from projector to 3D objects
 Is it just going to be about the mapping or is it done in combination with a performing art piece that requires lighting

The best   and 
the most expensive  are DLP 

Panasoniz DT -Z 21k  i.e.
I work a lot with Projektors, more DLP then LCD and i never saw this "rainbow" effect, so dont be nervous.
My favourit Projektors are DLP Stuff for sure, more brightness / lower weight and a much better behaviour with dark content.  Its no Fun when you want to have a blackout and you see a grey field on the stage.
So what was the question again ?! 
a solid machine you also can do some other stuff with :
DLP / 3000 Ansi-Lumen / Full Hd (1920 x 1080px)/ ~600~1000 €
You wont be able to get some Lensshift in this area.

I was thinking Christie D4K3560

I don't believe any of the inexpensive consumer grade projectors have lens shift available at all and they are all table-top which can be problematic for a lot of mapping application but should be OK for mapping on boxes.

What you think about this: 
http://www.optomausa.com/products/detail/HD141X the Optoma projectors are good or not ? This one (HD141X) seems to be abordable and with a great quality.

A review:

So if I want to use this to project on some boxes (approxi...  22 in x 18 in ) [a pyramid of 3 boxes height and maybe 4 or 6 boxes large] I should put my 
projector very far of the boxes.

				you can calculate your distance by yourselfe 
 
Throw Ratio 	1.48–1.62 (distance/width) 
1m far away = 1,48 - 1,62m wide picture
