want2reef: Where can you get the RK2 for $230?
Others: I am looking to get either the RK2 or the AC Jr. This thread is timely and very helpful. How rock-solid is the AC Jr.? I see the DC8 had a recall because of a bad ground. I'm leaning toward the AC Jr. because the RK2 is brand new and I think probably needs a firmware rev or 2 to get kinks worked out. I also like the AC programmability. The AC Jr. box looks kind of flimsy from the pics, though. My main immediate need is temp controller function, and timing on the lights, but I think I'll also go in for the pH monitor as well. Anyone have pics of their AC Jr. setup?
[edit] Also, is the group buy controller from PA one with the serial cable (switched input)?
