Looks great for the price.
Me and my mates bought a Grainfather together (and love it). We've been wanting to get another. We might get one of these instead and then modify it to be more like the GF.
A couple of issues (easily solved) with this KK one:
I don't agree (with the KK video) that recirc isn't important at this volume. From experience using the GF I know for sure that it is - and, if not recircing, temps at the bottom near the element can be very different than temps at the top of the grain bed. I'd definitely modify this KK model to include recirc. (Not recircing can also cause scorching near the element particularly in grain bills including rye etc. I know from due to my own stupid mistakes and forgetfulness).
Also that immersion chiller would be rubbish (residual heat in the stainless steel would make chilling it a long, tedious process. I'd solve that by either buying a counterflow chiller or no-chill.
Other than that it looks good. And the fact they're bringing out bigger volume versions is great!
Can anyone who has bought one tell me what controller it uses?
EDIT: Also, wouldn't that controller get too hot?
