The Vertex Cerebra is just a CAD drawing, so I wouldn't hold my breath on that one. You will see a touch screen from the other players before that one ever makes it to market. A proprietary touch screen isn't the smart way to go, when you can buy an Ipad for $550, or an HP Slate in Stir Crazy's case
If your short term and longterm needs are limited (PH, temp, ORP, ATO, lighting), then buy a Reefkeeper. If you have a larger system with a calcium reactor, prop pumps, or any other 0-10V devices then go with Apex, and if you don't mind paying double the cost and can't do it with Apex, then Profilux is the smart choice.
All of these manufacturers have very confusing or at least vague, product lists and descriptions. Be prepared for surprise extra costs for modules, expansion boxes, power bars, level sensors, calibration solutions, software, and solenoids.
If you like tech gear, then any of these are well worth the investment. If you are not technically inclined, then buy dedicated control devices. Sometimes it is convenient to carry all of your eggs in one basket, while other times... how does the saying go again?
