i've never looked at ORP, so i just stuck with the Aquacontroller Jr. I got the DC4's as i dont want to worry about the reliability of X-10s. Furthermore, the way i see it, i would have to buy heavy duty power strips to plug the modules in anyway. assuming i can fit 3-4 modules per strip that would take 3-4 strips (~120) and 12 modules (~$180) to control 12 devices (the max of the Jr). the DC4's from Premium aquatics are ~$100 each, so the cost comes out similar, but without the risk of X-10 and of course with a cleaner look.
The total ended up costing me about double the Reefkeeper, but now i can control 12 devices (rather than 8) plus i can control pH (which would have costed ~$200). so the cost comes out about the same, only with the added flexibility of the aquacontroller.
