Hi 811.
Our BT-LH80 just went belly-up a couple weeks ago, and Panny repair estimates over $2K to replace the LCD (the unit powers, but no image - just died between shoots). All that to say, when it comes back from Panasonic (unrepaired), the field-installable SDI module will be available. Any interest?
What are you hoping to get for it? Drop me a PM.
