For me, even the dual boiler is not worth it. A machine with a working PID (that has the offset documented and you can set it, not via vague presets) and you are set and properly equipped. Everything above are nice to have but unnecessary.
Here is an article about the issue: Boilergate
You can check yours by running some water via the steam wand, if you find any small black grinds in the cup, that is the coating peeling.
Did you check if it has the flaking issue? I bought one a week ago and it already has flakes through the steam wand. Seems like Gaggia is ignorant of the issue.
In the European market, it is priced similarly to a Lelit Bianca, which is the end game budget. The Silvia Pro X is about 400€ and the Elizabeth can be found for 900€ less, both new.
To me it seems that the pricing is just not right. And understand that I am not the target audience for this kind of machine.
