Wow. Good thing you didn't do any research. Unless you have the skills on Green Monti, you would be paying out the arse for all the welding these systems use. Not to mention the Blichmann pots do better with weldless due to the gauge... further not to mention that by welding you are at the mercy of the welder, who may or may not suck balls.
This system is extremely well designed and uses no new concepts that would need proof of concept. Everything here works. Willy did a great job implementing ideas and assembling the product. It is worth every penny he is asking.
Anyone who has build a system of this scale (or considerably smaller) will tell you the work and level of detail involved in finishing such a project without cutting corners.
I am sure your dick feels much bigger after knocking willy
Just wait it out Willy. Someone will come knocking eventually. Remilard just proves what I was talking about in my first post. People with no clue always think they have one.
