My company (startup, ~25 employees) also used the free version for several months (late '08 and early '09) but were disappointed with the sound quality (we, too, never tried the paid version). We used GoToMeeting for several months as well, but got fed up with frequent issues (dropped calls, failures to connect to join meetings, etc. almost daily). We now use WebEx. We've had very few issues and the quality is good, but the interface is a real pain in the ass to use. I'd be interested in hearing anyone's experience going from the free version to the paid one.
