I'd have to agree with this commenter. The old adage that "you get what you pay for" is as true for telepresence as it is for most things in life. I know that my company has had a great experience working with a firm called LifeSize Video Communications, out of Austin, TX. Their high definition videoconferencing has performed superbly in our experience. And while we could have cobbled something together on the cheap instead, the time and aggravation involved in putting these systems together and keeping them up and running would more than outweigh any savings.
