I don't think any of them work yet. I tried to get the Web Cam GO Plus and PC 300 Cam (New One) to work with the USB Camera utility. No go. They are supposed to be doing an OS X driver for the cameras as we speak, but it has been delayed. So don't be upset if it diesn't work yet. Also, some of the older cameras may not be supported - so don't be too upset if you have to go back to classic.
