Ron's rule (one of them, anyway) is that the easier it is for everyone, the less useful and informative it generally proves to be. While it's very likely that we'll pay too much for what we get, it's similarly unlikely that we'll get more than we pay for unless someone else pays the difference - which is generally unlikely. Like the laws of thermodynamics, you can't expect a sum return greater than the total investment. So it depends on what you need to know. Ron N
