USB Webcam with Speaker & Microphone

While most USB webcams feature a built-in microphone, how many of them actually has a speaker embedded within? This one does, retailing for an impossibly high $31.99. I personally don’t think that’s a fair price to pay, as one can expect less than decent audio quality to come out from it. Features include :-

• VGA @ 30 frames/second
• White Balance: Automatic
• Exposure Control: Automatic
• Flash Control: Automatic
