Can you help me find a web camera that is good in lowlight?

That's really a good idea of finding a webcam that works good even on low light. So if you are planning to use it for your notebook then I found this Logitech QuickCam Deluxe Webcam for as low as $36.75. With a stylish look and performance to match, QuickCam Deluxe for Notebooks provides a high quality video and audio experience that ensures you always look and sound your best. Logitech's RightLight Technology and RightSound Technology adjusts intelligently to produce the best possible video and audio, even in noisy or dimly-lit rooms.

How about this USB 3 LED PC Webcam Camera plus + Night Vision MSN, ICQ, AIM, Skype, Net Meeting and compatible with Win 98 / 2000 / NT / Me / XP / Vista for $7.75. You can connect with your world day or night using this Webcam with Night Vision. 6 LEDs will illuminate the darkness, and a high-resolution color sensor provides 24-bit true color. Twist the lens to focus it for an incredibly clear picture. Great for Skype, ICQ, AIM, MSN, or net meetings! Please note, this camera model is not compatible with Yahoo, and has no built-in microphone.

Also look at this Logitech QuickCam Orbit AF Webcam for $109.95. Enjoy image-perfect detail and clarity plus motorized tracking. Carl Zeiss optics and autofocus keep images razor sharp, even in extreme close-ups. It adjusts intelligently to produce the best possible images in dim or poorly backlighted settings.
