Options for Sea Quest air source replacement

[Mr. Blues]

I have on old circa 1991 Sea quest discovery BC with a sea quest air source that has seen better days ...i.e. the oral inflator/purge button is missing major parts. I like this arrangement but wonder what's compatible
with the old hose and pull dump design. Scuba pro's air 1?,2?, 3? etc. or other makes?
Looking for a plug and play idiot proof octo/reg? any ideas/upgrades etc.
Thanks for all replies

You may want to check the newer version of the AL air source. There maybe hose compatibility issues with other brands although the Scubapro and Atomic versions are better breathing.
