I'm looking to switch to all-grain in the next year but I want to spread out the cost so I'm looking to start purchasing the equipment now. The goal is to purchase equipment that will last me a while - quality is important.
I was looking at Blichmann, Spike, and Stout but there are several additions I have never heard of before and I haven't been able to find information about. For instance, Stout has a Tangential Inlet on their brew kettle and the hot liquor tank has a HERMS coil.
After seeing the Blichmann G2 at my LHBS, I was not impressed and doesn't think it's worth the money (personal opinion).
Where can I find information concerning these extra options and what is important?
Thanks
