My home brewing experiences are sadly limited to a buddy who had a air conditioned workshop, a couple of buckets and some 5 gallon glass jugs, and lots and lots of yeast.
My theory is that, just like electric smokers "idiot proof" things for the beginner, electric brewing must help reduce the learning curve tremendously. I don't know much about the wiring for the control box but everything else is just like playing with VERY adult Legos ... I'm a believer that you can never have too many hobbies (so long as I'm still single).
The guy who runs that site and sells the boxes and plans is a great guy and there are a lot of craft breweries using that stuff (just in larger volume, obviously). Besides ... I can make the beer that I use to add to my sauces or boil my brats!
