Has anyone tried this?  I think the price is great but I am cautious about purchasing it for our demo center without any information other than that offered by an aggressive marketing campaign.  Their return policy, when I inquired, seems to state that we can return it if it is broken.  I was looking for a "if for any reason this does not suit your needs or you are not satisfied" type return policy.  That does not mean it isn't good.  I just would like to hear from people in the field who have experience with this technology.  Thanks!
