The vessel is from Willis, but they are hit and miss if they have them in stock or even if they want to sell you something.
MrLard on the forums has just started importing a VERY similar model + has the spare bits to back them up, so if your looking for an English based seller contact him.
If you dont need the conical shape a standard stock pot will still produce excellent results.
As for brew length its designed for 100 with a capacity of 110 litres, so yes fewer brewdays but less clearing up

But for "banker" brews its ideal (albeit the Stout Kit is an unknown), I`m also working on a smaller one pot system for trial batches.
