I just saw it, Jeffrey ... thanks so much for providing an experienced opinion (which I lack at this point).
The reason I'm sticking with Gizmo for now is the sound quality is excellent ... I've talked to IMers from Sweden and London today, and they might as well have been down the street.
Also ... the conference call and ability to record on the spot without upgrade makes it very convenient for my line of work.
But ... please do keep me updated on anything else out there ... including Skype, that winds up being a better alternative.
Could use a few tips on audio conversion tools, as well.
