It certainly depends upon who you talk to re: wether the Orbe/Phantom will /does work. Michell says "yes" and many in England love it. While Artech, says "no." In either case both claim that you need the special acrylic arm board that Michell created for the Phantom. More pro vs con that I have found but I'd still like to hear from those with the proper set up.
As yet though I have not found anyone who has used the acrylic arm board. Many, use the original arm board not knowing it's too heavy. I am tinkering with the idea of doing the Phantom but would like to find out more.
