Heavy duty is a Cimbali HX. A quick look at the Alexia shows 1) plastic tubing under pressure, 2) vibe pump an inch (?) away from the boiler (cooler the better) and 3) no protection for the electrical contacts in the unlikely event of spraying water. Seems like typical prosumer construction to me. Before the flames start, I seen much much worse on some other prosumer machines. Seen pictures of plastic connectors for tubing under pressure and the controllers mounted very close to the boiler .. ouch. Pluses for the Alexia has an E61 group and a capillary thermostat.
Wesley, "heavy duty" is a four-group Synesso. And, since the OP is looking for a SBDU machine, both DB and HX suggestions aren't all that helpful to the OP.

My comment about the la Cimbali wasn't suppose to be a suggestion but frame of reference. Some people think that the Silvia is a heavy-duty espresso machine; I am more critical and consider the Cimbali to be heavy duty. There are SBDUs with no plastic pipes under pressure. There are SBDUs which do a good job of placing the pump in a cool location. There are SBDUs that provide some protection of the electrical parts from spraying water in the event of some leaks. I didn't want to mention any names and the OP realized that his machine was better than he originally thought.

I think my Nuova Simonelli Ellimatic is probably the toughest single boiler machine, though it's an HX. But it's made of all brass piping and metal parts. The only problem is the pump is a tad too close to the boiler. That and it's tiny water reservoir and drip tray.
