I'm building my 4 keg keezer with 2 dual tap Perlick towers. I'm looking for a quality temp controller that is accurate & user friendly for this project. I have a Johnson A419 on my ferm chamber that works well, but doesn't appear to be waterproof. I'd like to have the probe in water inside my keezer so it doesn't kick on/off so much. I want this to be deluxe, so i'm not necessarily looking for cheap, but good quality & easy to set up. Any suggestions? Thanks all!
