Sorry for not being clear. By this "But I want minimize frustration with camera choice (desktop with no built in cam)" I meant that I need to buy a cam and I want to know what works. I do not have one yet.

Thanks! 

Just be clear we were answering the OP's question, I suggest if you want advise on a webcam to get you start your own post asking that question, it makes life easier for everyone
