I bought the outdoor camera in the link below. This thing rocks! Crystal clear picture with pan, tilt and zoom. I got it for $199. They'll give you a deal if you talk to them.
It took a bit of time to get the port forwarding to work since I hadn't done it before, but they have a video on the enclose CD that shows how it's done.
My only complaint is that it's a bit of a hassle to mount the thing.
