Coming from the hot rodding hobby, there's an old saying, "cheap, fast, and good: pick two." In my experience, that applies to not just speed parts, but brewing too. (ok, maybe replace "fast" with "easy".) Everything has trade offs, the question is do those trade off align with your goals?
The trade offs for a no-boil beer doesn't align with my goals, so I don't plan on trying. YMMV.
