You're quite welcome. After you put together the controller and start using it, you'll be on here with me (and the others who use them) telling everyone how much you love it.
One of the nice benefits beyond precisely setting the ferment temp is the ability to, once it's done, touch a few buttons and cold crash the whole thing down to 36*F for 3-5 days before bottling/kegging to clarify the beer. And you never have to even touch the bucket/carboy until it's all done.
