I recently found VZOchat http://www.vzochat.com/ it is free and very simple and I think it gives the best video quality so far. I like it more than Yahoo, MSN, ISpQ and others that I tried before. I use it when I travel to see my family, however I am not sure I would use VZOchat for business. The same company has another service called ZoomCall http://www.zoomcall.com/ that they advertise for business use. ZoomCall is also free to try, but then you have to pay soemthing to use it. I tried them both side by side with my friend (we both have cable) and ZoomCall gave us even better qulity, but for my needs VZOchat is good enough.
