I'm toying with the idea of converting my 10 year old propane system to electric, so I'm reading about controllers. I'm looking at building a 50amp eHERMS system to make 10 gallon batches. I'm not really a DIY person, so I'm looking at off the shelf controllers. One thing I can't get my head around is why there is such a huge difference in cost between controllers. At one end of the spectrum you got two Brewcommanders at $750. On the other end, you got Kal's panel at $2695. In the middle, you have the Brew Buddy II. Obviously, these controllers take different approaches and have different components, but I'm having difficulty figuring out the pros and cons of each and what's actually worth paying for. Thoughts?
