Just about any electronics store or any online store. They are pretty cheap now days. I would suggest amazon as they often have the best deals and offer free shipping!
Probably buy a webcam, cuz i need one!
You will need a video call software such as Skype or you can use an online services. You will also need a webcam, most modern laptops have a webcam, if this isn't an option, you will have to buy an external webcam, they will run you anywhere from $10-$50 at Best Buy or similar stores.
you have to buy a webcam with a microphone
i dont think that you can get 1 for under $50
Buy another
Yes you can
The PhotoFast WebCam was announced in the summer of 2010 but there has been little sign since of any available to buy.
If you video chat a lot, or record a lot of videos sitting down at a desk, it is a good idea to buy a webcam.
you get a job!
I would look at the Colt Defender. it's under $50
You CAN webcam chat on Windows Live Messenger. When you are talking to someone, under their profile picture there should be a webcam button (if they have a webcam, that is). Click that and you can invite them to webcam chat with you.
