I have the Anvil kettle as well and I'm thinking about getting the Fermentation kit. One word of advice, Remove your dip tube after every boil/fermentation and give it a good scrub with a tube brush. I've found over a few boils, that unless you are scrubbing it out after each boil, it will build up some break/trub residue that may potentially harbor some nasties. The boil temps would probably keep this at bay, but never hurts to be thorough.
