Well, I can literally stand on top the vacuum easel of my biggest enlarger without deflecting the plane. It's that well built. But most people don't use machined steel easels weighing several hundred pounds. The colorhead itself requires a block and tackle to lift off for sake of any bulb change - gotta get to that task soon, once I'm certain my shoulder bursitis is fully healed. But in the meantime, the Durst L184 is quite competent for the slightly smaller color prints I'm doing at the moment. And yes, I'm "picky". All those seemingly little details cumulatively add up.
