Mine is on its way from Great Fermentations. I plan to retro fit onto my older gen BoilerMaker mash tun. Pretty excited to get it. I talked to John about in at NHC in San Diego. Pricey, yes, but I'd like better control, particularly out of the mash tun to boil copper during sparge. I hope this does it. Not sure it makes sense on the other pots (HLT, boil copper).
