Did you get to see one yet? Just a warning, the unit was originally designed to fit this with Mitsubishi CRT projectors, so they say it may not function fully with certain other brand projectors. I wanted to use it with my Barco Cine 7 but heard many contradictory views on whether it would work or not, so I dropped it in the end.
If you do a search, you may find some threads that actually shows some very good Japanese forum talk about how to use this unit with various proejctors. You can email TK Chan or Li On of this forum who are more knowledgeable about these units.
