Hi there, big bank of knowledge on the internet!

I'm building a video sampler to use in a show with a dance company. Now I want to move on from using my built-in isight cam to a USB cam that I can point at other stuff than my face ;-)

Do you have any advice on:

- Which camera I might use? Preferably a cam that I could use even if the lighting isn't really great - Do I need any special software to be able to get a live stream from my cam into jit.grab?

Thanks!!!
