According to BrewPi philosophy,the only piece of equipment needed from outside BrewPi store to have a fully functional HERMS setup is 3 Kettles.
As I am living in Europe, currently in The Netherlands, I have a bit diffuclty to find good kettles at decent prices. Until now I have seen good ones from Concord in the US which get quite expensive with Shipping + Import Taxes. In Europe the best price/quality I have seen are the ones from SS Brewtech which are still quite expensive.
I have seen that @Elco Kettles look quite nice. Would you advise where you got them?
Personally I am looking for something around 75-100 L but I think would be nice to set here some advices for future people.
