The PZ-1 looks very much like the ScubaPro MK10 internally. The nice think is the schematic shows all the required o-ring sizes to make your own kit. I wish all reg schematics had that o-ring detail on them. The only other items are the filter and the seat. The filter and seat look like the standards that are available form several sources, but hard to tell for sure without opening it up. You probably put together your own kit for $15 or less.
Would be a fun reg to service DIY, but that probably doesn't help you.
Hopefully @Jim Lapenta , or @Ulfhedinn have given you the leads you need for a non-DIY solution.
