Okay, I'm popping in those upside down timers in upside down receptacles. What is the transformer wattage max I should avoid going over? 300? 600? Feedback on how anyone's success in the field with intermattic timers is much appreciated. Also, any word yet on Unique, Cast, Kichler, etc. coming out with astronomical timers (module, built-in, or plug)? I think the intermattic is not very good quality for the amp loads we use, plus it's a little silly when you pop open the trans cover and the timer is upside and impossible to program that way. Radio Shack charges 5 bucks each for the battery that fits them, and they take two. This is very humorous, considering intermattic's unit is just over that.
