I feel your pain! When I was doing marine tanks those controllers were damned handy. I just roil at the thought of having to spend $120+ on one for 3 stupid timer functions. It gobsmacks me that there isn't a wide variety of these things on the market with any and all kinds of functions for not a lot of dough. It's not like they're using i7s in them. Also, on the battery backup function (just to go back to the Brinks junk) - on 2 of mine, they don't work. Laughable...if not pathetic.
Once in a while you can find those controllers (older versions) used in the $50 range, Nunster.
