I've used that model that I posted above about 10 times over the last few years. Seems to be pretty good. I have 3 of them installed at my house. Two on lighting transformers and 1 on my water feature.
I never really thought about the two outlets on the bottom much. Are those controlled by the astrological timer as well? So the Christmas lights would come on and off at the same time as the outdoor lighting system? That's kinda cool. (Although we don't install Christmas lights).
