Don't know what to tell you, but I've toured I-don't-know-how-many US/Canadian brewpubs and they were all single-step infusion set ups. I can't speak to your buddy's homebrew machine, but in many ways a home brewery can be much more flexible than a small commercial brewery. Generally speaking, to do proper step-mashing you need a separate vessel for heating the mash in addition to the lautering vessel, which is obviously more costly and takes up more space. You can do limited step mashing in a single mash vessel set up by adding more hot water, but there are limitations to what you can do there.
