Best small camera for dark rooms? (weddings and such)

[asylum]

Hello, I just ordered a Cannon S330 because of it's size, and 3X zoom rather them the S200 with the 2Xzoom. I thinking it might have been a wrong choice?
I take a lot of pictures in dark places such as Wedding halls and dark clubs. After I bought it I read that Sony's Digital cameras were better in low light situations. Is this true?
Otherwise any helpful hints for taking pictures in low lighted areas?

Thanks!

I own a Canon A40 Powershot and when I have to take pictures in dark rooms, I try and get as much natural light from windows or artificial light from lights, even bringing ones in from other rooms to light up the dark corners. You don't say if this is just a hobby or you do if professionally? If it is the last one then stand-alone lights that you plug in may be the only solution and they can be up to 200w to 300w. I know it can be very difficult to focus in dark areas so additional lighting is necessary.
