My Regal Cinema has this brand (looks like Plasmas) and the consession stand. They look gorgeous. I've never seen such sharpness and clarity. I want one. DO they sell them to general public?

Research indicates that the monitors you saw were 42" plasmas, were not manufactured by Christie, were rebranded (possibly NEC or Panny) specifically for this installation contract. Christie apparently only makes DLP and LCD projectors and one model of 40" LCD flat panel, as well as switching, control and communication gear tailored for high-resolution video presentation.

On a side note, kind of off topic, I've been seeing very nice looking plasmas popping up in the strangest places. Airport security stations for one. Some of these look nicer than consumer models I've seen demo'ed, but that could just be because of the content.
