Webcam suggestions?

I'd been meaning to get a webcam for about a month now, but hadn't yet gotten around to it. Do any of you have recommendations or suggestions? I know my coauthor Paolo would say to buy the cheapest $20 device I can find. But do the higher-resolution cameras add any value?

Also, our default webcam service would be Yahoo! Messenger, which my family and Joyce's family both use. If you'd like to see a Juliet webcast, it's probably good to either get an ID or convince Cliff to sign up for your service of choice.

In any case, please either add comments or send Cliff mail.

Thanks.
