Yes I've seen those, the ones we will be selling have a direct 23 pin RGB cable on them and they are also powered off of the 12 volt line on the amiga Video port.
no extra cables. just the box with a 2ft cord and 23pin plug.
The Sharp LCD I have is from 2008 and it doesn't support PAL (576i @ 50hz) when using Component Video. It only supports 50hz when using composite or S-Video.
