Wish I would have gotten rid of some, instead I tried to hold on, and lost most of my sps when trying to swap things.
If I didn't already have the ones I did, I wouldn't shy away from one. Since I have an ACIII running everything, there isn't a bonus at all to me to the stuff that already has the timers built in... And I don't like the idea of running that as an ATO either.. I mean, with the heat we've had this summer already, I'd have had to test and adjust way too many times.
Its likely I will just stick with these unless I get lucky enough to get forced into a calcium reactor someday.
