Hi RobbyG - I just wanted to take a moment to thank you for taking the large amount of time you have obviously put into compiling, sorting through, and then continually updating the information on these controllers. It's a fantastic resource for those looking to purchase a new controller or even see how their current controller stacks up against the competition.
I currently own an Aquacontroller II that runs my 180 gallon tank. However, I am planning to upgrade to a larger tank over the next two months and at the same time, will be looking at purchasing a new controller with Web access. Currently, the Profilux and the Aquacontroller III are in the front running.
IMO, the Profilux has a big plus and probably has a slight edge at the moment due to it's ability to control Tunzes. I read somewhere on RC that Neptune might be releasing something in the near future to control Tunzes, but other than that statement, they haven't said anything else. So, it could be months out and cost quite a bit.
So, the jury is still out on which controller I'm going to chose. But your spreadsheet is a great help in narrowing that choice down.
