bluewaterphoto.com also sells a version of the tray - I think it's a WeeFine brand - it is part of the WeeFine 7' monitor package. I'm sure they sell it separately as well.
Please let me know if you try transmitter as I saw the video on it and I am interested too. I would like to add an external monitor to my OM-1/Nauticam rig as well. I have been looking at the different options and if this worked it would be the most cost effective and smallest configuration for travel.
Good luck and let us know what you decide.
