I haven't seen them for a while. I looked at one but it really didn't hold enough cans for me. I eventually purchased a Breakmate. It's not "new" but we really like it, it serves fountain drinks out of a small unit. You can see a picture of mine in these pictures:
I have not seen one is a while either. When they first came out we bought one and it still works fine now, though we had a few service calls initially before they finally got the bugs worked out. It would have been nicer if it held at least a 12 pack on each level so I think the size/convenience is part of what did it in.
