A good observatory clock

[pmrid]

I'm looking at installing a decent clock in the observatory and am hunting suggestions.
It needs to be illuminated, and in red. It neds to be able to automatically synch via the Internet.
What do others think about showing local sidereal time as well as standard time?

I've looked at these before Peter - they update via an NTP server over ethernet and use 4" high 7-segment red LEDs. Very visible.
