I bought one exactly as pictured from this seller a while back and am very, very happy with it! It is well made and all welds are "sanitary" which to me means it's ground flat. It arrived sooner than I expected too. I have not had any leaks like the people in the above link.
My only complaint with it are the rubber gaskets that seal the lid to the hopper. I've had blow offs the last two batches and the gaskets have absorbed the beer and turned light brown. They are also ripping along their edge and will need to be replaced after a few more batches
