I personally am awaiting the release of the reefkeeper elite, it really looke like it is gonna be a nice unit. I currently have been using a Octopus 3000 unit which is basically the same as the aqaucontroller 3 high end unit. It cost about twice what the reefkeeper elite will cost, but I like several advantages to the reefkeeper. the reefkeeper can be flushmounted. which I like to make things very organised so it is a plus to me. and switching to a DC8 or DC$ is priceless. I currently use X10 modules, which also have an advantage of being used anywhere in the house. I control a kalk reactor in my down stairs and controll my tank in the middle level of the house and can control lights in my upstairs. the down side like fatman said is they are suceptable to radio interference. I have one light in my downstairs that if left on will keep my metal halides from cutting off on a different floor of the house! so if that were a calcium reactor there would be some serious trouble. anyway, all that to say DC8s and 4s are priceless. I have heard alot fo good things about the aquacontroller jr as well, my best friend uses one and loves it. it doesnt flush mount otherwise it might be more affordable. good luck with your purchase
