Did the shop say you couldn't get service parts or did they say they couldn't get service parts?
I have yet to find an Aqualung single hose reg from 1972 to the present that can't be serviced. For instance, Service Kit PN-900001 is the first stage kit for the following regs:
Conshelf XII (Introduced in 1972)
Conshelf XIV
Conshelf 20
Conshelf 21
Conshelf 22
Conshelf SE
Conshelf SE2
Conshelf SE3
Titan
So the same kit will do the Aqualung Conshelf/Titan 1st stages from 1972 up to today. I have never got into your 1st stage, but it may use the Aquarius kit, The 2nd stages look to be standard USD seconds and don't have any parts that are truly custom. As for the crack, that was common for regs like the SE/SE2 etc. and may, or may not, mean that the case needs to be replaced.
