Looking For A Camera...Appricate Your Help :)

[RIKI23]

Hello!
Im looking for a new digital camera but the important feature im looking for is the video quality. i usually take videos in parties where the lightning is not that good so i dont expect that much but i want the video resolution to be very good but the size to be normal. i almost bought the new canon tx1 but after reading that 13 minutes of video worth 4 gigabyte i immediately changed my mind. i saw sony dsc-w70 video quality and really liked it and the size is normal as well. do you have any suggestion about a camera even batter then the w70 but to be stills camera too because i dont want a video camera.
thanks so much for your help im so confused

Do you mean the size of the camera or the size of the video files? I'm confused, too
