What camera is good at dark?

I would like to shoot object with light projected onto it's surface (dots or lines) in dark environment. The object is small similar to the size of mobile phone. How can I archive good result on the light spots? most of them are blur or the color is not clear some blue color at the edge or strong white color in the middle of the spots.

What setting on the camera is suitable?
What camera should I buy? (the budget is around $400 us to $800 us)
Another setting on the light spot or environment should I take care?

Need more info.
Which camera used.
Aperture, shutter speed.
Did you use a tripod?
Does your camera have special settings for low light?

Better yet, how about a photo.

I have shot a photo with NIKON COOLPIX L11. The image has lot of background noise even in back environment (little red white spots noise on the surface). I only what the light spots which I cast/project onto the surface of the object. Here is link. http://community.webshots.com/album/...host=community

Any suggestion on what camera Model should I buy? I am not good at camera knowledge. Thks!!

Well, I have a Coolpix 11 - and I have to say I have tried everything to get a good picture in the "dark" or low light with it, and had NO results...nothing worked, even a tripod - so I would suggest another model, from what I read after I bought it, the coolpix is not good at low light, at all! I have been using it for a while and I can attest to that.

Good luck, no info about another model, I just got a canon, and am learning to become happy with it even in the total dark - I have gotten some great shots with out a tripod - though I am not a real photographer, so they are great/good to me but might be crap to someone who KNOWS photography! :D

go for canon
