Webcam Brand/Model Suggestions

TLDR: I am running out of time to buy a webcam for use with Skype on Debian, can anyone suggest a brand or model that is known to work? I'm asking for tips because I am on a tight timeline and the task is 5 hours drive away at a relative's house, where I'm going to install Debian 7. They have requested Skype, I've not used it nor even webcams before. I went to the local computer shop and plugged in a webcam and saw 0c45:62c0 in dmesg. But checking at home the Debian IRC bot "judd" says "Unknown device from unknown vendor". So I'm looking for tips to at least purchase something that will work. (I'm at work now so I cannot test anything.) Thanks for any assistance David
