[time-nuts] Affordable PoE 6-digit time displays?

My reason to hack up a nice clock display is because no matter what I can't
make my home brew stuff look as nice.
So to me its a pile of displays in a nice rack box that I hook a processor
to and do what ever I like.
Reversing out the display methods pretty easy as they are typically
multiplexed.
I use Truetime DC 468 7 segment panelplex displays this way. Just like the
looks.
Regards
