I am pondering the same thing, as an Fscan owner, and obvious recent indications from my docs, I begin to suspect that perhaps other devices, as you refer to, or methods of TREATMENT, such as radiant plasma, or stronger output devices may be the way to go. The Fscan is great for less serious conditions, and for scanning some 90% of what's out there, but falls short in these other areas perhaps, and I OWN and USE one :) Great posts!
