Serious....yes, especially if the 1st stage you have has the dry enviro seal rather than the oil type.
The T20 is mechanically identical to all the current Apeks 2nd stages. It's only known problem was a poor inhalation diaphragm that would "taco" after a few years....an easy replacement.

mmmmm......now looking at your pic it looks like you have the "Pioneer" balanced piston 1st stage.
Nothing wrong with it but that said USD/Aqualung make great diaphragm regs.....not so much balanced pistons.
Still, Uwatec gauges, Arctic and Apeks 2nd stages are still a nice deal.
.....I may be mistaken with IDing your 1st stage as it's a bit fuzzy.
