I just bought a Reef Angel. $219 and it comes ready out of the box to turn my daylights and actinics on separately, moonlight or Refugium light on when my main lights go off, 2 wave maker controls, heater control with temp monitor, main pump, and auto topoff with two float sensors, Plus PH monitor with included probe. Feeding mode, water change mode built in. Nothing else I saw matched that. You can add several expansion modules, more plugs, RF control of Exotec power heads, dimming and lightning effects for PWM LED, WIFI with iPhone, Android and web portal control.
There is a forum and tons of code you can copy and paste to upload. The owner has emailed me back with answers to questions very quickly.
