Reef keeper elite

Cyberjester has one. From what I've seen they are really nice, but it sounds like they are still missing some critical modules.

I've got one, So far its been a great unit, a little intimidating at first but once you start playing with it its pretty easy to understand.

Ya they are still working on some more modules but it is worth waiting. Very expandable!!

I have one, they are getting there. 
Not perfect yet, but I would still recomend them.
With what they have currently you can:
They have the
PC-4 modules that can be daisy chained.
SL-1 module gives readings on PH, temp, ORP, and can read 2 switches
NET module gives email alerts of alarms and provides remote access to view status of selected items
MLC module which can control 6 luner pods (2 lights per pod) on a true luner cycle
ALC module which is designed for control of advance lighting systems (IE Aqua Illuminations fixture)
The system is very easy to use and understand.
Actually the only thing I don't like about it is:
Seems like every time at this early stage there is a firmware update a bug sneaks into the system.
Took them 12 days to ship a small order of in stock items to me.
