Couldn't vote as there is a Reefkeeper Lite with variants, and the Elite with variants
Guess I'm in the minority so far. I use a Reefkeeper Elite.
From what I can tell from posts mine is much easier to program and has all the bell and whistle add-ons like Apex with a brand twist;
Apex supports the Ecotech MP/QD series while DA supports Tunze
DA also has additional modules like Apex;
Moonlights, dc pump controllers, dc light controllers, net modules etc etc ...
I went DA for the price and PC programmability
My unit supports up to 63 modules, and the new Archon supports up to 255 modules
