I know this thread was a flame war for a while...but I am glad to see it back on track. We seem to have an emotional tie to each of our systems and I can appreciate that.
It is interesting in the varied experiences between users of the DX1. I had the exact opposite experience. My setup was not challenging, a few small issues were resolved quickly, and I got what I wanted.
My main goal was to shorten my brew day, have manual/auto control to move liquor/wort, and have temperature control. I viewed the DX1 as more of a brew day manager...stepping though each phase either manually or automatically. My goals were met as I can set the DX1 to delay start before I even get out of bed. It fills the HLT to the calculated level, heats it to strike temp and fills the MLT(from the bottom), auto refills the HLT, and starts mashing using the HERMS coil. Thats when I show up and stir and have a cup of coffee while mashing. I am almost halfway done with brewing and just showed up.
I wasn't able to find a BCS system successfully operating this way, although it may exist. Good luck to all on their venture!
